[Phpwm] large sites that use AJAX

[pete graham]

I was talking to someone about web development the other day and they
wanted to know what AJAX was. After explaining it to them they asked
me which big sites use AJAX.

The only really big examples I could come up with of the top of my
head were Gmail, Flickr and the Wordpress admin interface. What
examples would you have given?

Also which AJAX sites do you think have the best/novel interfaces?
