Aside from finally getting to meet a few of my fellow MCA friends, the best part about TechEd had to be the Cabanas. I would much rather sit and talk to a bunch of people smarter than me that go attend one of those over packed sessions (though I go to quite a few of those). My favorite "session" was an ad hoc one on Thursday morning. I didn't realize it, but Kirk actually caught it on film. That morning Julie, Rich, Don, Clemens, Christian, and I kicked around topics ranging from System.Transactions to Borland development tools of yesteryear (we even talked about Visual Basic right Rich :P ).
This years TechEd kicked ass. I have three pages of notes, and about 20 follow up items that I need get started on before I forget. To everyone I talked to, thanks for giving me the time to knock ideas off you (or for the good ones you gave me).
