I think the biggest problem with reddit is that the simplest subreddit name is going to attract the largest audience, and if you don't like the moderators or community there, then there's nothing you can do about it. There's only one /r/politics, and if you don't like it then you'll have to move to, say, /r/notpolitics, which is going to have less visibility and a smaller community simply because of its name. What would help would be, for lack of a better term, "namespaced" subreddits. There wouldn't be a /r/politics, there'd be a /r/namespace1/politics and a /r/namespace2/politics, and there'd effectively be no problem with visibility: if someone's looking for a subreddit to discuss politics, then there isn't a default, and you'll have to explicitly choose which community and moderation style you want. The best way to implement this would be a federated reddit, with each server being it's own namespace. If you don't like federated-reddit1.com/r/politics, then move to federated-reddit2.com/r/politics. There'd be a problem with bubbles, but that wouldn't be any worse than what already exists.
