Last year, I was able to attend the Gov 2.0a conference in Oklahoma City. The 2011 sequel is being held this weekend, at the Skirvin Hotel in Oklahoma City. Unfortunately, I won't be able to make it this year, but I highly recommend this conference if you can do it (registration closes tomorrow).
From the website:
The second annual Gov 2.0a conference is focused on applications of technology to government problems. The conference will be a forum to learn about successful Gov 2.0 applications through case studies, to learn about best practices for Gov 2.0 applications, and to network with other professionals from city and state organizations, community groups, non-profits and the private sector who share interest in the application of technology to improve the functioning of our government.For more information on this truly outstanding event, go to Gov20a.com.
You will have the chance to see over a dozen talks on the Gov 2.0 themes of Open Data, Crowd Sourcing, and Citizen Participation. The speakers are nationally known Gov 2.0 experts who will share their experiences and lessons learned that will inform your own efforts to improve government. You will have the opportunity to meet and talk with speakers and attendees during one of the many scheduled breaks and networking events.
