I have been busy :)
Currently I'm writing an article for MSDN detailing the internals of the ScriptManager; and so between that and work I have had next to no spare time to really do anything else. When the article if done then I'll have plenty of time for exploring ASP.net, AJAX, .Net and the like...but for now, I gotta get this article done!
Thanks....
(about another couple days, probably)
