Along with Scott Guthrie, Mark was one of the fathers of ASP.NET - is he presenting at PDC...what's he working on now? The talks given by Mark (and Rob Howard) at the Wrox Professional ASP developers' conference in London in 1999 were my first taste of the then NGWS and ASP+ (seem to remember Dino Esposito trying to guess what .NET was - which was pretty amusing at the time :-)) . Whatever he's working on, you can bet it'll be pretty interesting... Anyone....?
