'Congress on Facebook' goes live

Facebook on Thursday debuted its "Congress on Facebook" hub to showcase members' online profiles and communicate news about the social network and the lawmakers who use it.

The page builds off the early success of the site's "Government on Facebook" page, introduced in 2009. That hub has helped federal agencies create more than 400 pages with fans into the millions, according to Facebook.

"More than 300 members of Congress use Facebook in an official capacity to communicate and connect with their constituents and we're excited showcase some of the most innovative uses of our platform on Capitol Hill," said Tim Sparapani, Facebook's public policy director. "We hope this will encourage even more use of social technologies like Facebook by politicians and government agencies to interact with and serve their constituents."
