How do down votes work?
NathanKP: The best way to use your new downvote powers for good is to read the HN commenting guidelines:http://ycombinator.com/newsguidelines.htmlIf a comment doesn't satisfy those guidelines then downvote it.  Some people also downvote comments that they disagree with, but I typically avoid that tendency, and only downvote comments that come across as overly negative/critical, or are completely, obviously wrong.
