Kevin: The US government collects and publishes mountains of data that are easily used for these types of visualisations. The Obama administration will release most of the content from WhiteHouse.gov under public domain and licenced under Creative Commons Attribution 3.0. I wonder whether this will drive even more open data publication by the US government.

Kevin: "The Washington Post today is launching Who Runs Gov, a site primarily made up of a database of personalities in the United States government. If you're looking for info on your state's senator or representative, or details about a cabinet or high-ranking military official, it looks like the site could be a valuable resource." It's a wiki running on MindTouch. Edits will not go live until approved by Washington Post staff.
