Not an answer, but there is no way to be 100% sure about the web framework they are using without having access to their servers. The best you can do is make guesses based on the structure of the website, or comments in code, etc. As for JavaScript libraries, you can just click View Source in your browser. :) –  Sasha Chedygov May 31 '10 at 8:55
