I just picked up on David Temkin's:The Ajax reality distortion field via Steve and Marc.
David makes some very good points, but what I personally think is really interesting about the current state of DHTML/Ajax is that some web frameworks are starting to integrate Ajax functionality directly into their libraries.
As a developer this lifts a huge weight off your shoulders by allowing you to to take advantage of DHTML/Ajax without having to worry about wether your code is compatible with all the major browsers.
The framework does all the heavy lifting so you can spend your time designing the application.
