It's not the most used language, actually, though I don't think it's your fault for misreading the chart. Ruby on Rails and "Ruby on Rails Token" were split into two different categories, based on how they figured out the site was using Rails. If you combine those two categories, ruby has higher usage than php. Not to defend the php hate, of course. Just to point out that it's not actually the most popular language, despite the misleading graph.
