I attended and spoke at WordCamp Houston which was my first WordCamp. It was a very well organized event and probably could have even been stretched to 2 days judging by the fact that it sold out 2 months before the event.

I got to hear sessions from Aaron Brazell (@TechnoSailor) and Stephanie Leary (Writer of: Beginning WordPress 3) as well as a few sessions from the Blogger track.

Matt was very accessible and spent time talking to a lot of attendees as well as attending 3 after parties and sitting in on a session in each time slot (he was in mine and I didn't even notice till the very end).
