I'd like to see a run-through of various website that make heavy use of AJAX to see how well the do/do not render.

For example, Google Docs is often mentioned and Facebook as well, but what about Yahoo Mail, Zoho, Meebo, Google reader, etc...

Also, how about DivX? MPEG4 is supposedly supported. How does Stage6 look?

Those are the ones that immediately come to mind.
