Laurel Ruma and I have chosen a powerhouse (if I do say so myself) program committee to help us as co-chairs of the upcoming Gov 2.0 Expo in May 2010 in Washington, DC. It's a fairly diverse bunch - check them out here.
These are the people that will help us put together the keynote speakers, the "rapid fire" five-minute talks, the panels, and the workshops. There's still an open call for proposals at the main website. I encourage you to submit something before the Jan 6 deadline!
