I get that he may be under pressure to make unpopular decisions, but I still can't believe that he invited the whole of Reddit to an AMA and then just answered 14 questions - as if that wouldn't turn out to be the PR disaster it was. Trying to think of a rational explanation beyond "just incompetent" is really hard after that - unless he has some hidden agenda that involves sabotaging Reddit. There's surely no way he couldn't have known that AMA would be a disaster.
