Overrated is not Disagree. Read the FAQ
Concentrate more on promoting than on demoting. Try to be impartial about this; simply disagreeing with a comment is not a valid reason to mark it down. The goal here is to share ideas, to sift through the haystack and find needles, and to keep spammers and griefers in check.
Sometimes comments are disproportionately up-moderatedâ"this probably means several moderators saw it at nearly the same time, and their cumulative scores exaggerated its merit. (Example: A knock-knock joke at +5, Funny.) Such a comment is Overrated.
