What are good reasons to leave positive reputation?
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 isn’t a good reason to give positive reputation.
