Yet once again I saw a perfectly reasonable post marked off-topic, and I had to mark it as unfair. It was not exactly on-topic, but it was a valid and useful reply to the comment. Why a moderator would waste points marking it off-topic is beyond me. Were there not enough good comments that day? Are there some whose only mission in life is to to promote personal agendas? I do not know.
I try very hard to limit my negative moderation to truly harmful posts(goatse, etc). It seems if a post relates incorrect information, that post will invariable attract comments that correct the error, and those replies will usually get modded higher than the original comments.
