Microsoft recently released the v. 1.0 of ASP.NET AJAX "Atlas" and I've attended a demo about Atlas and find it really cool. Just simple drag and drop, cut and paste viola... you have an AJAX enabled website. It also include AJAX toolkit (extenders) which can be downloaded for free.

Microsoft offers new certification for ASP.NET Developers named MCDDP which stands for Microsoft Ceritified Drag-and-Drop Professional..
