I'm sorry, but you are incorrect. It may not be officially supported, but they are doing it.

Check out the results for the 1st link (aakilfernandes.com/uiji.html) and then check the source code. You'll see that the entire body of the page is written with javascript.

I stand corrected - sort of - a bit more research shows the reality is "some dynamic/Ajax content" is indexed by Google, and not all search engines (i.e. Bing) are doing it yet.

For example, same search on Bing - http://www.bing.com/search?q=uiji.js
