At the Gov 2.0 Summit Tim O'Reilly and Representative John Culberson spoke about social media and Congress. It was a lively conversation that is definitely worth watching. (My question was the first one taken from the audience about 12 minutes in ;-)

The thing that stood out for me was that although Tim and Representative Culberson are not in agreement on most issues, they were able to have a great conversation and come to understanding on mutual areas of interest.
