Add subsections to the "user submitted" filter

Since this new feature was put in, the community as a whole seems to be exploding in rage. Of course keep the popularity/virality section as it has been. but simple sections like cute animals, animated gifs, facebook reposts, OC uploads, sad comics, funny comics, political bs, etc. would help out by allowing users interested in that content to be exposed to it, limiting the downvotes all around and encouraging an imgurian userbase that doesn't hate each other to form.
