several times over the past week i've been wanting to down vote some of the stories that have made the front page for various reason. i read in the faq that you should only flag a story if it goes against HN guidelines. the faq states that while there are down vote arrows on comment (after the user reaching a certain threshold) there are never any on stories themselves.
so after all of that, my question is: how do you exactly down vote a story on HN without feeling icky cause you flagged it?
Flagging puts stuff in the moderation queue to be reviewed for abuse / spam. Please don't abuse it for other purposes.
Downvotes exist, but are hidden until you've posted more than some threshold I forget the exact value of.
The idea is to help prevent the downvote button from being even more of a "I don't like what you're saying but can't muster a convincing response to it" button than it already is, while making it convincingly difficult to manipulate via spam accounts.
It's much better at the second than the first, people being what they are, but it does seem to help with both at least enough to justify the feature's continued existence.
