Government 2.0 in action

I'm usually skeptical of Internet hype (how the Web has changed everything), but this is definitely something new: Peter R. Orszag, director of the Office of Management and Budget, is engaging, via his own blog, with the following bloggers in a debate over health-care reform and its effects on the nation's finances: Richard Posner, Virginia Postrel, and Mickey Kaus.

I wonder: does he have to clear his posts with anyone?
