This is what I think reddit should do. There are endless arguments there over whether something belongs in /r/pics, /r/funny, /r/LI5 or /r/askscience, etc.<p>I always thought that a lot of what we call "subreddits" are actually orthogonal tags that apply to posts. Think about it, if there's a funny picture of a naked girl, why isn't that simultaneously in /r/pics, /r/funny, and /r/nsfw?
