Ask HN: How to design a reputation-system like Stack Overflow?

5 pointsAarvay1 comment

Suggest the best way to design a "fair" reputation system. (Ex: StackOverflow, HackerNews(karma)) Support your answer with a mathematical reasoning!

Thanks.

Mathematical reasoning? Sounds like one of those interview questions. How about ↑ == ++rep and ↓ == --rep ?
