I tend to be sparse with my -- votes. Generally, I only -- rude, non-productive posts or non-constructive criticism. Disagreeing with someone is not a reason that I --, whether I agree with someone or not isn't a measure of the quality of their post. Besides, sometimes the post that I may disagree with was the inspiration for some great discussion, in which case I will often give it a ++. Other than just good quality posts, I always ++ a node that I add to my PN, if it was worth remembering, it's gotta be good for something ;) and I will usually ++ the creator of a thread where I reply, too.
