I think it's a little unfair towards Reddit. Any community large enough will be taken over by trolls if nothing else for the fact that they're the ones making the most noise. Subreddits are perfect way to contain those people away from others since the majority won't be posting in niché subreddits, and those few who do can be moderated. If anything might be a lesson on community design it might be to put up a few more "barriers" between subreddits and the general population and think about how to control interaction between them.
