For purposes of full disclosure, well, I've just accepted a full board membership at the Sunlight Foundation, as in "sunlight is the best disinfectant" pertaining to corruption in high places.
These folks run Congresspedia, which is pretty much Wikipedia for the US Congress. They work with other groups to expose corruption, increasingly important as more and more scandals arise. I recommend Members of Congress under Investigation.
They're saying a coupla excessively nice things about me; please ignore.
