Whenever there's an AMA on reddit from someone interesting, the scum floats to the top. Occasionally, you get something interesting but most of the time the AMAs are vapid. When a politician does an AMA, people upvote questions about weed or posts complaining that the US is a police state. When Paul Krugman did an AMA, libertarians raided the thread, downvoted all of the other questions, and upvoted stupid shit like questions about the legitimacy of Austrian economics.
