I've got to say, I've been really impressed by the number and quality of the attendees from Microsoft -- Simon Guest, Howard Dierkin, Peter Provost, Scott Guthrie, Scott Hanselman... and I'm sure I missed others. These folks have been extremely willing to listen to feedback, and to give us a bit of insight into the workings of Microsoft.
Ironically enough, the room full of agile devs didn't know about the MS Agile Development Center.
