Community moderated sites like Reddit and Stackoverflow rely almost solely on volunteer moderators to police things. Is there a better model where these volunteers are compensated with dollars so that they are more aligned. In a post yesterday, Gina Bianchini (Ning, Mightybell) says that "I believe the best business model for community platforms like Reddit are those that offer moderators and the platform revenue-sharing opportunities." Is this necessary for long-term success? It's easy to say "oh they should just do this" but community is tough so I would love to hear from people who run community driven sites, work(ed) at them or have been moderators.
