I think "Dangerous" could perhaps stay on. "Outdated" would probably be better off replaced with "Invalid" or something of that sort. I don't think we need "Works for me" or an analog of it at all: I don't entirely disagree with Quintec's suggestion of "Interesting/Cool/Wow" but showing your support for an answer is what upvotes are for. An "Interesting!" reaction wouldn't add anything meaningful (unlike "Works for me" on sites where that applies).
