I am an avid redditor with a mostly dead facebook account, so I agree that the content is better, but it's different networks entirely. Reddit has still held on to its psuedo-anonymous roots, and thus hasn't lived up to the "social" part of the social network. The people still consumuning content on facebook are doing so because that's where their friends are. You know the people that feel a need to tag their friends…

The best real discussion (especially for ongoing topics and events) I've seen is still on old-school forums like SomethingAwful.

I'd like to see a modern forum site where anyone can create a subforum and moderate it themselves the way anyone can create a subreddit on Reddit.
