This is potentially a very interesting/useful site. My only problem is with some of the questionable statistics it's showing, that might suggest their dataset is not strictly representative. The time zones in particular seem to be significantly skewed compared to their respective population distributions. There's also a suspiciously large number of UTC0 fingerprints, which suggests they might have a large number of crawlers/bots in their dataset.

Thanks for the website, it's very interesting.

From their statistics, it seems that WebGL gives far less info than things like the list of fonts, the Canvas properties, or the audio input, and more comparable to effective height of the screen (or even just user agent in my case, using Firefox on Linux, though I have to admit I'm surprised about that: 0.02% sounds really low).

Using firefox on a mac is basically enough to put me as all time unique on that site.

Me too, my user agent was something like 0.01%.
