For a project that's trying to improve documentation and documentation visibility, arewefirstyet.com is a pretty horrible site. I had no idea what was going on until I read the jsconf speech. Also, (this is nitpicky, but) you might want to reverse the vertical axis of your graph to emphasize that #1 is a good thing (and make the range 1-250, not 0-250).

Of course, if you only want 'insiders' looking at arewefirstyet.com, then what I said doesn't matter.
