I'd like to help you with your comment being grayed out, but excitingly, since a few weeks HN doesn't let me upvote comments anymore -- the vote button disappears and the unvote link appears, but the color doesn't budge, neither does the commenter karma. I can upvote stories just fine, but not comments. So, yeah.
