I was looking at my conference Tee from a Wrox conference in 2000.  I thought it was interesting the placement of C# and how its become such a big name now, definitely worth a top billing.  Also you'll notice the original name for ASP.NET listed as "ASP+".  I think I still may like that name better.  Hopefully at the next PDC, they'll have Avalon and Indigo on the conference Tee so I can post that Tee in 2010 when the names have been changed by marketing to something functional like Windows Ultra-Graphic Rated-M Control System and Really Good Communication System.
