Hi Ray. This is interesting, and the data about supporting tools like Git, RequireJS, and CoffeeScript is probably valid. But since you're a well-known jQuery blogger and you're on the jQuery team, it's hardly surprising to see the higher numbers for jQuery and it's related libraries (underscore, etc.).

I'm not saying you're being biased on purpose or anything. I'm just saying that I don't see how the results could have been anything different from what they are, given the audience that frequents your blog. There are clearly a very large number of people using Angular, ExtJS, GWT, etc. It's just highly likely that don't read (or even know about) this blog. ;-)
