I'm pretty cautious when it comes to downvoting. A comment would have to factually incorrect, FUD, abusive or utterly pointless and stupid for me to downvote it. If in doubt, I just leave the comment be to the mercy of other HN'ers. Another option is to upvote a child comment so there's more balance in the discussion.
