Javascript framework popularity
javascript, jquery, mootools, scriptaculous, yui
Solution
I don't know of anything specifically like that, though Google Trends is probably a pretty good indication of popularity. For example, you can compare jquery and mootools:

Problem
Are there any resources comparing the adoption rates of the various javascript frameworks similar to tcpi? Basically the number of sites using a particular framework on a time-line would be ideal.
