There's no need to whip a dead horse (I've probably been griping about the ASP.NET AJAX Framework for too long), but... Jon Galloway and a group of other notable gurus (K. Scott Allen, Scott Koon, and Kevin Dente) have started a podcast, their latest segment sparked my interest since it covered ASP.NET AJAX and AJAX Libraries / Frameworks in general.

I share their sentiments so I thought I'd post a brief but choppy transcript:

[ASP.NET AJAX] ... does offer some some nice features, they did try to take some of the common pieces of the CLR that [.NET Developers are] used to working with and move that down into a JavaScript library. So you get classes like a WebRequest class that wraps the XMLHttpRequest ... and they have a StringBuilder, and they added methods that we're more accustom with ...

that's wonderful, but I don't find myself needing those extensions all that often. If you want to do strictly client-side programming then something like jQuery offers you a lot more capabilities to do things that you really want to do client-side like sorting and CSS selectors. ... That stuff is easy to do with an Update Panel and ASP.NET, but Update Panels aren't always the best solution to use. ...

the goals with ASP.NET AJAX was to integrate into the ASP.NET server-side model ... that's great for ASP.NET, but it needs more client-side features. ... It works if your thinking from the ASP.NET control perspective, but if you look at it outside the ASP.NET model there are a lot easier ways to do it. ...

ASP.NET AJAX [development] seems to have come to a standstill I'm not seeing a lot of development in that area and the rest of these [AJAX] Frameworks are doing monthly releases. Every month that goes by [the ASP.NET AJAX Framework] falls further and further behind ... it needs to evolve.
