== Lists of browsers == 

 Would someone please explain why are there lists of browsers that support/doesn't support Ajax in the article?  I don't see much value in both lists because whether an ajax application works properly is more down to the application itself than the browser.  Every case is different and such an over-generalisation won't help the reader understand much more, if not outright mis-leading.  Case in point: people would tend to say "Google Calendar does not support Safari" rather than the other way round, ie "Safari does not support Google Calendar".
