Tyndmyr writes "In conjunction with the previously covered Knol system, Google has recently released Knol Debates, where users can vote for and discuss various topics. First up, presidential debates, representing topics from any party, and with some commentary being given by the libertarian Cato Institute. Unfortunately, patent law and technology questions are still rather poorly represented. Oddly enough, Knol Debates doesn't even appear to be in beta. The system makes use of Google Moderator to select questions."
