I don't really agree with how I've seen meta stuff being enforced. I was under the impression that the meta channels were just for discussing meta stuff when you don't want to argue about whether or not the meta stuff is actually real, but that if you do want to try to prove that it is real then it can go where ever, but the way that it seems to be enforced is that if the mods think that it's meta, then it goes in the meta channels regardless of what sort of discussion you are looking for
