I'd kinda like a dislike button because the forums are full of threads of multiple pages of people going "NOOOOOOO!" at the OP, whereas threads about things which people want are buried because they get liked instead of commented on. And so, we all look like a bunch of whiny babies, instead of being able to just dislike and move on, and stuff that we can agree that we want just fades out, where devs will never see it.
