This is an interesting study into how Reddit works, but I have to say that I'm fine with the fact that Reddit is neither a meritocracy or democracy when it comes to how posts make it to the front page. I'd rather not see any more funny or aww posts on the front page than are already there (I can go to their subreddits directly when I want to).
In fact, I'd rather see a variety of posts from subreddits I don't usually go to or usually follow. I want to see thing I don't already follow. Most posts I end up liking are ones I find in the subreddits I visit. I'd like my front page to give me posts from other unsubscribed subreddits so that I may end up expanding which subreddits I'm subscribed to.
