Reddit is searching for something, but I don't think they've introduced a single feature that makes it better since they added subreddits. They've added and removed community chat rooms [0], they still have some other kind of chat that I don't know if anyone uses, when I happen to visit new Reddit there's some kind of streaming broadcasts that I don't see anyone liking. And of course the redesign, but I suspect that their metrics show that a majority of users like it, so it's just old users like med that are put off by it. Recently they introduced Topics [1], but it's not supported by the API, so you need to use their apps.
