Joshua Tauberer, a grad student at U. Penn, has created an amazing legislative tracking service, GovTrack.us, which won the top prize in the Technorati Developer’s Contest. The site’s automated monitoring services are free, and the data is obtained from federal sources including THOMAS and the websites of the U.S. House and Senate. Users may track bills, issues or committees, representatives, or topics. Daily or weekly email updates are available for registered users, as well as news feeds. The site also includes blog postings on legislation, by authors registered with the site to have their comments appear on the GovTrack Blog.
