Summer of Apollo
It’s July, 2019. You know what that means? The 50th anniversary of the Apollo 11 mission is this month.
I’ve already got serious moon fever, and if you’d like to join me, I have some recommendations…
Watch the Apollo 11 documentary in a cinema. The 70mm footage is stunning, the sound design is immersive, the music is superb, and there’s some neat data visualisation too. Watching a preview screening in the Duke of York’s last week was pure joy from start to finish.
Listen to 13 Minutes To The Moon, the terrific ongoing BBC podcast by Kevin Fong. It’s got all my favourite titans of NASA: Michael Collins, Margaret Hamilton, and Charlie Duke, amongst others. And it’s got music by Hans Zimmer.
Experience the website Apollo 11 In Real Time on the biggest monitor you can. It’s absolutely wonderful! From July 16th, you can experience the mission timeshifted by exactly 50 years, but if you don’t want to wait, you can dive in right now. It genuinely feels like being in Mission Control!

Audio I listened to in 2018
I wrapped up last year with a list of some of the best audio I listened to in 2017. This year I huffduffed about 260 pieces of audio, so I could do a similar end-of-year list for 2018. But I thought I’d do something a little different this time.
It seems like podcasting is going from strength to strength with each passing year. Some friends of mine started new podcasts in 2018. Matt started Hobby Horse, where he talks to people about their tangential obsessions. Meanwhile Khoi started Wireframe, a jolly good podcast about design.
Apart from the trend of everyone having their own podcast these days, there’s also been a trend for quite short and manageable “seasons” of podcasts. See, for example, Horizon Line by Atlas Obscura, which is just four episodes long. Given the cherry-picking nature of my usual audio consumption (the very reason I made Huffduffer in the first place), this trend suits me quite well. There have been a few podcast runs in 2018 that I can recommend in their entirety.
The Secret History Of The Future is a collaboration between Seth Stevenson and Tom Standage, one of my favourite non-fiction authors. They look at modern technology stories through the lens of the past, much like Standage has done in books like The Victorian Internet. There are annoying sponsor blurbs to skip past, but apart from that, it’s a top-notch podcast.
I discovered Settling The Score this year. It’s a podcast all about film scores. The two hosts have spent the year counting down the top 25 scores in the American Film Institute’s list of (supposedly) greatest scores in American cinema history. It’s a pleasure to listen to them take a deep dive into each film and its score, analysing what works and what doesn’t. It will also make you want to rewatch the movie in question.
By far my favourite podcast listening experience this year was with Stephen Fry’s Great Leap Years. It’s just six episodes long, but it manages to tell the sweep of human history and technology in an entertaining and fascinating way. I’ll admit I’m biased because it dwells on many of my hobby horses: the printing press, the telegraph, Claude Shannon and information theory. There are no annoying sponsorship interruptions, and best of all, you’ve got the wonderful voice of Stephen Fry in your earholes the whole time. Highly recommended!
So there you have it: three podcasts from 2018 that are worth subscribing to in their entirety:

A framework for web performance
Here at Clearleft, we’ve recently been doing some front-end consultancy. That prompted me to jot down thoughts on design principles and performance:
We continued with some more performance work this week. Having already covered some of the nitty-gritty performance tactics like font-loading, image optimisation, etc., we wanted to take a step back and formulate an ongoing strategy for performance.
When it comes to web performance, the eternal question is “What should we measure?” The answer to that question will determine where you then concentrate your efforts—whatever it is your measuring, that’s what you’ll be looking to improve.
I started by drawing a distinction between measurements of quantities and measurements of time. Quantities are quite easy to measure. You can measure these quantities using nothing more than browser dev tools:
- overall file size (page weight + assets), and
- number of requests.
I think it’s good to measure these quantities, and I think it’s good to have a performance budget for them. But I also think they’re table stakes. They don’t actually tell you much about the impact that performance is having on the user experience. For that, we need to enumerate moments in time:
- time to first byte,
- time to first render,
- time to first meaningful paint, and
- time to first meaningful interaction.
There’s one more moment in time, which is the time until DOM content is loaded. But I’m not sure that has a direct effect on how performance is perceived, so it feels like it belongs more in the category of quantities than time.
Next, we listed out all the factors that could affect each of the moments in time. For example, the time to first byte depends on the speed of the network that the user is on. It also depends on how speedily your server (or Content Delivery Network) can return a response. Meanwhile, time to first render is affected by the speed of the user’s network, but it’s also affected by how many blocking elements are on the critical path.
By listing all the factors out, we can draw a distinction between the factors that are outside of our control, and the factors that we can do something about. So while we might not be able to do anything about the speed of the user’s network, we might well be able to optimise the speed at which our server returns a response, or we might be able to defer some assets that are currently blocking the critical path.
|1st meaningful paint||
|1st meaningful interaction||
So far, everything in our list of performance-affecting factors is related to the first visit. It’s worth drawing up a second list to document all the factors for subsequent visits. This will look the same as the list for first visits, but with the crucial difference that caching now becomes a factor.
|First visit factors||Repeat visit factors|
|1st meaningful paint||
|1st meaningful interaction||
Alright. Now it’s time to get some numbers for each of the four moments in time. I use Web Page Test for this. Choose a realistic setting, like 3G on an Android from the East coast of the USA. Under advanced settings, be sure to select “First View and Repeat View” so that you can put those numbers in two different columns.
Here are some numbers for adactio.com:
|First visit time||Repeat visit time|
|1st byte||1.476 seconds||1.215 seconds|
|1st render||2.633 seconds||1.930 seconds|
|1st meaningful paint||2.633 seconds||1.930 seconds|
|1st meaningful interaction||2.868 seconds||2.083 seconds|
I’m getting the same numbers for first render as first meaningful paint. That tells me that there’s no point in trying to optimise my font-loading, for example …which makes total sense, because adactio.com isn’t using any web fonts. But on a different site, you might see a big gap between those numbers.
I am seeing a gap between time to first byte and time to first render. That tells me that I might be able to get some blocking requests off the critical path. Sure enough, I’m currently referencing an external stylesheet in the
head of adactio.com—if I were to inline critical styles and defer the loading of that stylesheet, I should be able to narrow that gap.
My point is, you’re going to see very different distributions of numbers depending on the kind of site you’re testing. There’s no one-size-fits-all metric to focus on.
Now that you’ve got numbers for how your site is currently performing, you can create two new columns: one of those is a list of first-visit targets, the other is a list of repeat-visit targets for each moment in time. Try to keep them realistic.
For example, if I could reduce the time to first render on adactio.com by 0.5 seconds, my goals would look like this:
|First visit goal||Repeat visit goal|
|1st byte||1.476 seconds||1.215 seconds|
|1st render||2.133 seconds||1.430 seconds|
|1st meaningful paint||2.133 seconds||1.430 seconds|
|1st meaningful interaction||2.368 seconds||1.583 seconds|
See how the 0.5 seconds saving cascades down into the other numbers?
Alright! Now I’ve got something to aim for. It might also be worth having an extra column to record which of the moments in time are high priority, which are medium priority, and which are low priority.
|1st meaningful paint||Low|
|1st meaningful interaction||Low|
Your goals and priorities may be quite different.
I think this is a fairly useful framework for figuring out where to focus when it comes to web performance. If you’d like to give it a go, I’ve made a web performance chart for you to print out and fill in. Here’s a PDF version if that’s easier for printing. Or you can download the HTML version if you want to edit it.
I have to say, I’m really enjoying the front-end consultancy work we’ve been doing at Clearleft around performance and related technologies, like offline functionality. I’d like to do more of it. If you’d like some help in prioritising performance at your company, please get in touch. Let’s make the web faster together.

Monday, May 14th, 2018
Thank you. Thank you very much, Mike; it really is an honour and a privilege to be here. Kia Ora! Good morning.
This is quite intimidating. I’m supposed to open the show and there’s all these amazing, exciting speakers are going to be speaking for the next two days on amazing, exciting topics, so I’d better level up: I’d better talk about something exciting. So, let’s do it!
Yeah, we need to talk about capitalism. Capitalism is one of a few competing theories on how to structure an economy and the theory goes that you have a marketplace and the marketplace rules all and it is the marketplace that self-regulates through its kind of invisible hand. Pretty good theory, the idea being that through this invisible hand in the marketplace, wealth can be distributed relatively evenly; sort of a bell-curve distribution of wealth where some people have more, some people have less, but it kind of evens out. You see bell-curve distributions right for things like height and weight or IQ. Some have more, some have less, but the difference isn’t huge. That’s the idea, that economies could follow this bell-curve distribution.
But, without any kind of external regulation, what tends to happen in a capitalistic economy is that the rich get richer, the poor get poorer and it runs out of control. Instead of a bell-curve distribution you end up with something like this which is a power-law distribution, where you have the wealth concentrated in a small percentage and there’s a long tail of poverty.
That’s the thing about capitalism: it sounds great in theory, but not so good in practice.
The theory, I actually agree with, the theory being that competition is good and that competition is healthy. I think that’s a sound theory. I like competition: I think there should be a marketplace of competition, to try and avoid these kind of monopolies or duopolies that you get in these power-law distributions. The reason I say that is that we as web designers and web developers, we’ve seen what happens when monopolies kick in.
We were there: we were there when there was a monopoly; when Microsoft had an enormous share of the browser market, it was like in the high nineties, percentage of browser share with Internet Explorer, which they achieved because they had an enormous monopoly in the desktop market as well, they were able to bundle Internet Explorer with the Windows Operating System. Not exactly an invisible hand regulating there.
But we managed to dodge this bullet. I firmly believe that the more browsers we have, the better. I think a diversity of browsers is a really good thing. I know sometimes as developers, “Oh wouldn’t it be great if there was just one browser to develop for: wouldn’t that be great?” No. No it would not! We’ve been there and it wasn’t pretty. Firefox was pretty much a direct result of this monopoly situation in browsers. But like I say, we dodged this bullet. In some ways the web interpreted this monopoly as damage and routed around it. This idea of interpreting something as damaged and routing around it, that’s a phrase that comes from network architecture
As with economies, there are competing schools of thought on how you would structure a network; there’s many ways to structure a network.
One way, sort of a centralised network approach is, you have this hub and spoke model, where you have lots of smaller nodes connecting to a single large hub and then those large hubs can connect with one another and this is how the telegraph worked, then the telephone system worked like this. Airports still pretty much work like this. You’ve got regional airports connecting to a large hub and those large hubs connect to one another, and it’s a really good system. It works really well until the hub gets taken out. If the hub goes down, you’ve got these nodes that are stranded: they can’t connect to one another. That’s a single point of failure, that’s a vulnerability in this network architecture.
It was the single point of failure, this vulnerability, that led to the idea of packet-switching and different network architectures that we saw in the ARPANET, which later became the Internet. The impetus there was to avoid the single point of failure. What if you took these nodes and gave them all some connections?
This is more like a bell-curve distribution of connections now. Some nodes have more connections than others, some have fewer, but there isn’t a huge difference between the amount of connections between nodes. Then the genius of packet-switching is that you just need to get the signal across the network by whatever route works best at the time. That way, if a node were to disappear, even a relatively well-connected one, you can route around the damage. Now you’re avoiding the single point of failure problem that you would have with a hub and spoke model.
Like I said, this kind of thinking came from the ARPANET, later the Internet and it was as a direct result of trying to avoid having that single point of failure in a command-and-control structure. If you’re in a military organisation, you don’t want to have that single point of failure. You’ve probably heard that the internet was created to withstand a nuclear attack and that’s not exactly the truth but the network architecture that we have today on the internet was influenced by avoiding that command-and-control, that centralised command-and-control structure.
Some people kind of think there’s sort of blood on the hands of the internet because it came from this military background, DARPA…Defence Advance Research Project. But actually, the thinking behind this was not to give one side the upper hand in case of a nuclear conflict: quite the opposite. The understanding was, if there were the chance of a nuclear conflict and you had a hub and spoke model of communication, then actually you know that if they take out your hub, you’re screwed, so you’d better strike first. Whereas if you’ve got this kind of distributed network, then if there’s the possibility of attack, you might be more willing to wait it out and see because you know you can survive that initial first strike. And so this network approach was not designed to give any one side the upper hand in case of a nuclear war, but to actually avoid nuclear war in the first place. On the understanding that this was in place for both sides, so Paul Baran and the other people working on the ARPANET, they were in favour of sharing this technology with the Russians, even at the height of the Cold War.
The World Wide Web
In this kind of network architecture, there’s no hubs, there’s no regional nodes, there’s just nodes on the network. It’s very egalitarian and the network can grow and shrink infinitely; it’s scale-free, you can just keep adding nodes to network and you don’t need to ask permission to add a node to this network. That same sort of architecture then influenced the World Wide Web, which is built on top of the Internet and Tim Berners-Lee uses this model where anybody can add a website to the World Wide Web: you don’t need to ask for permission, you just add one more node to the network; there’s no plan to it, there’s no structure and so it’s a mess! It’s a sprawling, beautiful mess with no structure.
And it’s funny, because in the early days of the Web it wasn’t clear that the Web was going to win; not at all. There was competition. You had services like Compuserve and AOL. I’m not talking about AOL the website. Before it was a website, it was this thing separate to the web, which was much more structured, much safer; these were kind of the walled gardens and they would make wonderful content for you and warn you if you tried to step outside the bounds of their walled gardens into the wild, lawless lands of the World Wide Web and say, ooh, you don’t want to go out there. And yet the World Wide Web won, despite its chaoticness, its lawlessness. People chose the Web and despite all the content that Compuserve and AOL and these other walled gardens were producing, they couldn’t compete with the wild and lawless nature of the Web. People left the walled gardens and went out into the Web.
And then a few years later, everyone went back into the walled gardens. Facebook, Twitter, Medium. Very similar in a way to AOL and Compuserve: the nice, well-designed places, safe spaces not like those nasty places out in the World Wide Web and they warn you if you’re about to head out into the World Wide Web. But there’s a difference this time round: AOL and Compuserve, they were producing content for us, to keep us in the walled gardens. With the case of Facebook, Medium, Twitter, we produce the content. These are the biggest media companies in the world and they don’t produce any media. We produce the media for them.
How did this happen? How did we end up with this situation when we returned into the walled gardens? What happened?
Facebook, I used to wonder, what is the point of Facebook? I mean this in the sense that when Facebook came along, there were lots of different social networks, but they all kinda had this idea of being about a single, social object. Flickr was about the photograph and upcoming.org was about the event and Dopplr was about travel. And somebody was telling me about Facebook and saying, “You should get on Facebook.” I was like, “Oh yeah? What’s it for?” He said: “Everyone’s on it.” “Yeah, but…what’s it for? Is it photographs, events, what is it?” And he was like, “Everyone’s on it.” And now I understand that it’s absolutely correct: the reason why everyone is on Facebook is because everyone is on Facebook. It’s a direct example of Metcalfe’s Law.
Again, it’s a power-law distribution: that the value of the network is proportional to the square of the number of nodes on a network. Basically, the more people on the network the better. The first person to have a fax machine, that’s a useless lump of plastic. As soon as one more person has a fax machine, it’s exponentially more useful. Everyone is on Facebook because everyone is on Facebook. Which turns it into a hub. It is now a centralised hub, which means it is a single point of failure, by the way. In security terms, I guess you would talk about it having a large attack surface.
Let’s say you wanted to attack media outlets, I don’t know, let’s say you were trying to influence an election in the United States of America… Instead of having to target hundreds of different news outlets, you now only need to target one because it has a very large attack surface.
It’s just like, if you run WordPress as a CMS, you have to make sure to keep it patched all the time because it’s a large attack surface. It’s not that it’s any more or less secure or vulnerable than any other CMS, it’s just that it’s really popular and therefore is more likely to be attacked. Same with a hub like Facebook.
OK. Why then? Why did we choose to return to these walled gardens? Well, the answer’s actually pretty obvious, which is: they’re convenient. Walled gardens are nice to use. The user experience is pretty great; they’re well-designed, they’re nice.
The disadvantage is what you give up when you gain this convenience. You give up control. You no longer have control over the content that you publish. You don’t control who’s going to even see what you publish. Some algorithm is taking care of that. These silos—Facebook, Twitter, Medium—they now have control of the hyperlinks. Walled gardens give you convenience, but the cost is control.
The Indie Web
This is where this idea of the indie web comes in, to try and bridge this gap that you could somehow still have the convenience of using these beautiful, well-designed walled gardens and yet still have the control of owning your own content, because let’s face it, having your own website, that’s a hassle: it’s hard work, certainly compared to just opening up Facebook, opening a Facebook account, Twitter account, Medium account and just publishing, boom. The barrier to entry is really low whereas setting up your own website, registering a domain, do you choose a CMS? There’s a lot of hassle involved in that.
But maybe we can bridge the gap. Maybe we can get both: the convenience and the control. This is the idea of the indie web. At its heart, there’s a fairly uncontroversial idea here, which is that you should have your own website. I mean, there would have been a time when that would’ve been a normal statement to make and these days, it sounds positively disruptive to even suggest that you should have your own website.
I have my own personal reasons for wanting to publish on my own website. If anybody was here back in the…six years ago, I was here at Webstock which was a great honour and I was talking about digital preservation and longevity and for me, that’s one of the reasons why I like to have the control over my own content, because these things do go away. If you published your content on, say, MySpace: I’m sorry. It’s gone. And there was a time when it was unimaginable that MySpace could be gone; it was like Facebook, you couldn’t imagine the web without it. Give it enough time. MySpace is just one example, there’s many more. I used to publish in GeoCities. Delicious; Magnolia, Pownce, Dopplr. Many, many more.
Now, I’m not saying that everything should be online for ever. What I’m saying is, it should be your choice. You should be able to choose when something stays online and you should be able to choose when something gets taken offline. The web has a real issue with things being taken offline. Linkrot is a real problem on the web, and partly that’s to do with the nature of the web, the fundamental nature of the way that linking works on the web.
When Tim Berners-Lee and Robert Cailliau were first coming up with the World Wide Web, they submitted a paper to a hypertext conference, I think it was 1991, 92, about this project they were building called the World Wide Web. The paper was rejected. Their paper was rejected by these hypertext experts who said, this system: it’ll never work, it’s terrible. One of the reasons why they rejected it was it didn’t have this idea of two-way linking. Any decent hypertext system, they said, has a concept of two-way linking where there’s knowledge of the link at both ends, so in a system that has two-way linking, if a resource happens to move, the link can move with it and the link is maintained. Now that’s not the way the web works. The web has one-way linking; you can just link to something, that’s it and the other resource has no knowledge that you’re linking to it but if that resource moves or goes away, the link is broken. You get linkrot. That’s just the way the web works.
But. There’s a little technique that if you sort of squint at it just the right way, it sort of looks like two-way linking on the web and involves a very humble bit of HTML. The
rel attribute. Now, you’ve probably seen the
rel attribute before, you’ve probably seen it on the
link element. Rel is short for relationship, so the value of the
rel attribute will describe the relationship of the linked resource, whatever’s inside the
href; so I’m sure you’ve probably typed this at some point where you say
rel=stylesheet on a
link element. What you’re saying is, the linked resource, what’s in the
href, has the relationship of being a style sheet for the current document.
link rel="stylesheet" href="..."
You can use it on
A elements as well. There’s
rel values like
prev for previous and
next, say this is the relationship of being the next document, or this is the relationship of being the previous document. Really handy for pagination of search results, for example.
a rel="prev" href="..." a rel="next" href="..."
And then there’s this really silly value,
a rel="me" href="..."
Now, how does that work? The linked document has a relationship of being me? Well, I use this. I use this on my own website. I have
A elements that link off to my profiles on these other sites, so I’m saying, that Twitter profile over there: that’s me. And that’s me on Flickr and that’s me on GitHub.
a rel="me" href="https://twitter.com/adactio" a rel="me" href="https://flickr.com/adactio" a rel="me" href="https://github.com/adactio"
OK, but still, these are just regular, one-way hyperlinks I’m making. I’ve added a
rel value of “me” but so what?
Well, the interesting thing is, if you go to any of those profiles, when you’re signing up, you can add your own website: that’s one of the fields. There’s a link from that profile to your own website and in that link, they also use
a rel="me" href="https://adactio.com"
I’m linking to my profile on Twitter saying,
rel=me; that’s me. And my Twitter profile is linking to my website saying,
rel=me; that’s me. And so you’ve kind of got two-way linking. You’ve got this confirmed relationship, these claims have been verified. Fine, but what can you do with that?
Well, there’s a technology called RelMeAuth that uses this, kind of piggy-backs on something that all these services have in common: Twitter and Flickr and GitHub. All of these services have OAuth, authentication. Now, if I wanted to build an API, I should probably, for a right-API, I probably need to be an OAuth provider. I am not smart enough to become an OAuth provider; that sounds way too much like hard work for me. But I don’t need to because Twitter and Flickr and GitHub are already OAuth providers, so I can just piggy-back on the functionality that they provide, just be adding
Here’s an example of this in action. There’s an authentication service called IndieAuth and I literally sign in with my URL. I type in my website name, it then finds the
rel=me links, the ones that are reciprocal; I choose which one I feel like logging in with today, let’s say Twitter, I get bounced to Twitter, I have to be logged in on Twitter for this to work and then I’ve authenticated. I’ve authenticated with my own website; I’ve used OAuth without having to write OAuth, just by adding
rel=me to a couple of links that were already on my site.
Why would I want to authenticate? Well, there’s another piece of technology called micropub. Now, this is definitely more complicated than just adding
rel=me to a few links. This is an end-point on my website and can be an end-point on your website and it accepts POST requests, that’s all it does. And if I’ve already got authentication taken care of and now I’ve got an end-point for POST requests, I’ve basically got an API, which means I can post to my website from other places. Once that end-point exists, I can use somebody else’s website to post to my website, as long as they’ve got this micropub support. I log in with that IndieAuth flow and then I’m using somebody else’s website to post to my website. That’s pretty nice. As long as these services have micropub support, I can post from somebody else’s posting interface to my own website and choose how I want to post.
In this example there, I was using a service called Quill; it’s got a nice interface. You can do long-form writing on it. It’s got a very Medium-like interface for long-form writing because a lot of people—when you talk about why are they on Medium—it’s because the writing experience is so nice, so it’s kind of been reproduced here. This was made by a friend of mine named Aaron Parecki and he makes some other services too. He makes OwnYourGram and OwnYourSwarm, and what they are is they’re kind of translation services between Instagram and Swarm to micropub.
Instagram and Swarm do not provide micropub support but by using these services, authenticating with these services using the
rel=me links, I can then post from Instagram and from Swarm to my own website, which is pretty nice. If I post something on Swarm, it then shows up on my own website. And if I post something on Instagram, it goes up on my own website. Again I’m piggy-backing. There’s all this hard work of big teams of designers and engineers building these apps, Instagram and Swarm, and I’m taking all that hard work and I’m using it to post to my own websites. It feels kind of good.
There’s an acronym for this approach, and it’s PESOS, which means you Publish Elsewhere and Syndicate to your Own Site. There’s an alternative to this approach and that’s POSSE, or you Publish on your Own Site and then you Syndicate Elsewhere, which I find preferable, but sometimes it’s not possible. For example, you can’t publish on your own site and syndicate it to Instagram; Instagram does not allow any way of posting to it except through the app. It has an API but it’s missing a very important method which is post a photograph. But you can syndicate to Medium and Flickr and Facebook and Twitter. That way, you benefit from the reach, so I’m publishing the original version on my own website and then I’m sending out copies to all these different services.
For example, I’ve got this section on my site called Notes which is for small little updates of say, oh, I don’t know, 280 characters and I’ve got the option to syndicate if I feel like it to say, Twitter or Flickr. When I post something on my own website—like this lovely picture of an amazingly good dog called Huxley—I can then choose to have that syndicated out to other places like Flickr or Facebook. The Facebook one’s kind of a cheat because I’m just using an “If This Then That” recipe to observe my site and post any time I post something. But I can syndicate to Twitter as well. The original URL is on my website and these are all copies that I’ve sent out into the world.
OK, but what about…what about when people comment or like or retweet, fave, whatever it is they’re doing, the copy? They don’t come to my website to leave a comment or a fave or a like, they’re doing it on Twitter or Flickr. Well, I get those. I get those on my website too and that’s possible because of another building block called webmention. Webmention is another end-point that you can have on your site but it’s very, very simple: it just accepts pings. It’s basically a ping tracker. Anyone remember pingback? We used to have pingbacks on blogs; and it was quite complicated because it was XML-RPC and all this stuff. This is literally just a post that goes “ping”.
Let’s say you link to something on my website; I have no way of knowing that you’ve linked to me, I have no way of knowing that you’ve effectively commented on something I’ve posted, so you send me a ping using webmention and then I can go check and see, is there really a link to this article or this post or this note on this other website and if there is: great. It’s up to me now what I do with that information. Do I display it as a comment? Do I store it to the database? Whatever I want to do.
And you don’t even have to have your own webmention end-point. There’s webmentions as a service that you can subscribe to. Webmention.io is one of those; it’s literally like an answering service for pings. You can check in at the end of the day and say, “Any pings for me today?” Like a telephone answering service but for webmentions.
And then there’s this really wonderful service, a piece of open source software called Bridgy, which acts as a bridge. Places like Twitter and Flickr and Facebook, they do not send webmentions every time someone leaves a reply, but Bridgy—once you’ve authenticated with the
rel=me values—Bridgy monitors your social media accounts and when somebody replies, it’ll take that and translate it into a webmention and send it to your webmention end-point. Now, any time somebody makes a response on one of the copies of your post, you get that on your own website, which is pretty neat.
It’s up to you what you do with those webmentions. I just display them in a fairly boring manner, the replies appear as comments and I just say how many shares there were, how many likes, but this is a mix of things coming from Twitter, from Flickr, from Facebook, from anywhere where I’ve posted copies. But you could make them look nicer too. Drew McLellan has got this kind of face-pile of the user accounts of the people who are responding out there on Twitter or on Flickr or on Facebook and he displays them in a nice way.
Drew, along with Rachel Andrew, is one of the people behind Perch CMS; a nice little CMS where a lot of this technology is already built in. It has support for webmention and all these kind of things, and there’s a lot of CMSs have done this where you don’t have to invent this stuff from scratch. If you like what you see and you think, “Oh, I want to have a webmention end-point, I want to have a micropub end-point”, chances are it already exists for the CMS you’re using. If you’re using something like WordPress or Perch or Jekyll or Kirby: a lot of these CMSs already have plug-ins available for you to use.
Those are a few technologies that we can use to try and bridge that gap, to try and still get the control of owning your own content on your own website and still have the convenience of those third party services that we get to use their interfaces, that we get to have those conversations, the social effects that come with having a large network. Relatively simple building blocks:
rel=me, micropub and webmention.
But they’re not the real building blocks of the indie web; they’re just technologies. Don’t get too caught up with the technologies. I think the real building blocks of the indie web can be found here in the principles of the indie web.
There’s a great page of design principles about why are we even doing this. There are principles like own your own data; focus on the user experience first; make tools for yourself and then see how you can scale them and share them with other people. But the most important design principle, I think, that’s on that list comes at the very end and it’s this: that we should 🎉 have fun (and the emoji is definitely part of the design principle).
I also think we should remember the original motto of the World Wide Web, which was: let’s share what we know. And over the next few days, you’re going to hear a lot of amazing, inspiring ideas from amazing, inspiring people and I hope that you would be motivated to maybe share your thoughts. You could share what you know on Mark Zuckerberg’s website. You could share what you know on Ev Williams’s website. You could share what you know on Biz Stone and Jack Dorsey’s website. But I hope you’ll share what you know on your own website.

For the shortest month of the year, February managed to pack a lot in. I was away for most of the month. I had the great honour of being asked back to speak at Webstock in New Zealand this year—they even asked me to open the show!
I had no intention of going straight to New Zealand and then turning around to get on the first flight back, so I made sure to stretch the trip out (which also helps to mitigate the inevitable jet lag). Jessica and I went to Hong Kong first, stayed there for a few nights, then went on Sydney for a while (and caught up with Charlotte while we were out there), before finally making our way to Wellington. Then, after Webstock was all wrapped up, we retraced the same route in reverse. Many flat whites, dumplings, and rays of sunshine later, we arrived back in the UK.
As well as giving the opening keynote at Webstock, I did a full-day workshop, and I also ran a workshop in Hong Kong on the way back. So technically it was a work trip, but I am extremely fortunate that I get to go on adventures like this and still get to call it work.
