Okay, so the current Criticism Policy states the following:
Even "meh" counts as content, because it succinctly expresses "this didn't grab me". So does "I agree with what so-and-so said" or even "^this". An emoticon, an insulting macro, or "lol" is not content; it's spam. ("lol" could mean almost anything, whereas "meh" means one thing.)
I don't agree with this. Thoughts?
