If only people understood the real information war is won by evidence and argumentation instead of blanket downvoting. A lot of the stuff in those communities is nonsense, but that's part of freedom of the press. I can see the argument for downvoting falsehood, but as I noted in a prior post (now past payout) about web2.0 social media, our goal here should be discourse even if we're dealing with Brandolini's Law.
