Raw data is both an oxymoron and a bad idea; to the contrary, data should be cooked with care.

Some lovely data visualisation here.

If you ever need to pull up some case studies to demonstrate the business benefits of performance, Tammy and Tim have you covered.

If you’re in need of some long-term perspective right now—because, let’s face it, the short-term outlook is looking pretty damn bleak—then why not explore some of Max Roser’s data visualisations? Have a look at some of the global trends in inequality, disease, hunger, and conflict.

The Government Digital Service have published the results of their assistive technology survey, which makes a nice companion piece to Heydon’s survey. It’s worth noting that the most common assistive technology isn’t screen readers; it’s screen magnifiers. See also this Guardian article on the prevalence of partial blindness:
Of all those registered blind or partially sighted, 93% retain some useful vision – often enough to read a book or watch a film. But this can lead to misunderstanding and confusion

Some good-lookin’ stats from a responsive redesign:
Total page views, a metric we were prepared to see go down with the redesign, are up by 27%. Unique visitors per week are up 14% on average and visits per week are up on average 23%.

I heartily concur with Luke’s call for sharing of data:
If you’ve had success with a responsive design, my plea to you is to please share what you’ve learned.
I’m going to see if I can get some Clearleft clients to open up.

A great breakdown of mobile traffic to The Guardian website over time.

The fascinating story of how a dream team of geeks helped Obama to victory. Personally, I think it’s all about the facial hair. I mean, how could they lose with Trammell’s beard to guide them?

David takes a look at worldwide trends in web browsing, pointing out where mobile traffic exceeds desktop …and we’re not necessarily talking about smartphones here either.
It would be possible to travel from the Niger Delta on the west coast of Africa, to the horn of Africa on the east coast, without passing through a country where people surf more on desktop than a mobile phone.

Luke collates some useful mobile browsing statistics once again. Most of it is quite US-centric, but this closing point is a whopper:
36 countries more than doubled their Opera Mini user bases in one year.

A really fascinating analysis by Jason into the apparent disparity in web browsing between Android and iOS devices: it turns out that the kind of network connection could be a big factor.

This is may just be the best thing on the internet about data visualisation and statistics. And sex.
