Chris recently documented the results from his survey which asked:
Is it useful to distinguish between “web apps” and “web sites”?
There is just nothing but questions, exemptions, and gray area.
This is something I wrote about a while back:
Like obscenity and brunch, web apps can be described but not defined.
The results of Chris’s poll are telling. The majority of people believe there is a difference between sites and apps …but nobody can agree on what it is. The comments make for interesting reading too. The more people chime in an attempt to define exactly what a “web app” is, the more it proves the point that the the term “web app” isn’t a useful word (in the sense that useful words should have an agreed-upon meaning).
Tyler Sticka makes a good point:
By this definition, web apps are just a subset of websites.
I like that. It avoids the false dichotomy that a product is either a site or an app.
But although it seems that the term “web app” can’t be defined, there are a lot of really smart people who still think it has some value.
I think Cennydd is right. I think the differences exist …but I also think we’re looking for those differences at the wrong scale. Rather than describing an entire product as either a website or an web app, I think it makes much more sense to distinguish between patterns.
Let’s take those two modifiers—behavioural and informational. But let’s apply them at the pattern level.
The “get stuff” sites that Jake describes will have a lot of informational patterns: how best to present a flow of text for reading, for example. Typography, contrast, whitespace; all of those attributes are important for an informational pattern.
The “do stuff” sites will probably have a lot of behavioural patterns: entering information or performing an action. Feedback, animation, speed; these are some of the possible attributes of a behavioural pattern.
But just about every product out there on the web contains a combination of both types of pattern. Like I said:
Is Wikipedia a website up until the point that I start editing an article? Are Twitter and Pinterest websites while I’m browsing through them but then flip into being web apps the moment that I post something?
Now you could make an arbitrary decision that any product with more than 50% informational patterns is a website, and any product with more than 50% behavioural patterns is a web app, but I don’t think that’s very useful.
Take a look at Brad’s collection of responsive patterns. Some of them are clearly informational (tables, images, etc.), while some of them are much more behavioural (carousels, notifications, etc.). But Brad doesn’t divide his collection into two, saying “Here are the patterns for websites” and “Here are the patterns for web apps.” That would be a dumb way to divide up his patterns, and I think it’s an equally dumb way to divide up the whole web.
What I’m getting at here is that, rather than trying to answer the question “what is a web app, anyway?”, I think it’s far more important to answer the other question I posed:
Why do you want to make that distinction? What benefit do you gain by arbitrarily dividing the entire web into two classes?
I think by making the distinction at the pattern level, that question starts to become a bit easier to answer. One possible answer is to do with the different skills involved.
For example, I know plenty of designers who are really, really good at informational patterns—they can lay out content in a beautiful, clear way. But they are less skilled when it comes to thinking through all the permutations involved in behavioural patterns—the “arrow of time” that’s part of so much interaction design. And vice-versa: a skilled interaction designer isn’t necessarily the best at old-skill knowledge of type, margins, and hierarchy. But both skillsets will be required on an almost every project on the web.
So I do believe there is value in distinguishing between behaviour and information …but I don’t believe there is value in trying to shoehorn entire products into just one of those categories. Making the distinction at the pattern level, though? That I can get behind.
Incidentally, some of the respondents to Chris’s poll shared my feeling that the term “web app” was often used from a marketing perspective to make something sound more important and superior:
Perhaps it’s simply fashion. Perhaps “website” just sounds old-fashioned, and “web app” lends your product a more up-to-date, zingy feeling on par with the native apps available from the carefully-curated walled gardens of app stores.
Approaching things from the patterns perspective, I wonder if those same feelings of inferiority and superiority are driving the recent crop of behavioural patterns for informational content: parallaxy, snowfally, animation patterns are being applied on top of traditional informational patterns like hierarchy, measure, and art direction. I’m not sure that the juxtaposition is working that well. Taking the single interaction involved in long-form informational patterns (that interaction would be scrolling) and then using it as a trigger for all kinds of behavioural patterns feels …uncanny.
