It perplexes me that this is being treated like an either/or. It is not. In reality subreddits see a constantly exploding entropy as users try to fix a broken mechanism of correlation -- the fact that I like gaming doesn't mean that I like the same thing as every other reader of /r/gaming, for instance. Just fix that by splitting off into /r/truegaming, or maybe /r/games, or maybe...
