Raincity has been heading south to Gnomedex for several years, but this was the rookie year for MC.
A few words that come to mind:
Inspiring. Information overload. Intelligence. Empowering. New friends. Connection. Gogogo-non-stop. Ideas. Geeks Should Not Name Things. Collaboration. Geekery. Creative. Exhausted :)

Appropriately enough, Gnomedex 06 commenced with Dave Winer presenting a Washington State Proclamation: June 30, July 1st, 2006: RSS Days, directly from the office of Washington State Governor Christine O. Gregoire. What pull.
