please vote according to the quality and relevance of the comment, not how much you like the content. Vote up to signal agreement if you must, but don't vote down if the comment is clearly on topic and well written.

On behalf of all those who suffer from extreme karma-loss-aversion, I want to second this message. Please don't downvote just because you disagree on substance.

(I came close to deleting a recent comment of mine that was downvoted shortly after being posted. It's now at +12.)
