What are good and bad things to give positive repu

Reputation should be given to people who post meaningful, helpful, and thoughful posts. Any post that contributes to the thread in a positive way probably deserves positive reputation. This does not mean that you agree with what was said; the point brought up may be completely opposite to what you believe, but it may be a good point nonetheless, and worthy of a pat on the back. Giving positive reputation to someone because they are your friend and deserve to have a few more green dots next to their name probably isn't a good reason to give positive reputation.
