Justin, you are such a victim here. AJAX was never meant for more than data transactions. Many of these "usability" tools contain a little ajax and a lot of crap (old DHTML dogs wrapped in new, shiny, heavy graphics) Dojo, scriptaculous, MooFx... all of them... have _ONE_ AJAX request. And any component that they have that doesn't interact with a remote data source is not an AJAX component. It is a UI component.

Don't get me wrong. They have their place and can make some dog ugly applications seem friendly ... but if you put lipstick on a pig... it's still a pig.
