Two points -- what you're describing is a republic moreso than a democracy, and those are pretty sticky indeed. Reddit is also not a democracy -- it's a series of benevolent dictatorships, where the content is decided on by anarchistic vote, but can be controlled ultimately through a supreme leader, empowered by the virtue of their age (the oldest member of the subreddit gets to decide the content of that subreddit).
