I've got the karma to burn that I don't really care about the points. But aside from the "downvote is not a disagree button," twice in a row I clicked submit on a comment and by the time the page loaded I was at 0. I mean it was so quick that I wondered if 0 was the new default! I noticed a few other people with perfectly reasonable comments that were grey, too. It seemed unusual. I've been around long enough to have a sense of what's usual.
