IMO it boils down to how to give uses a 'reputation score' in a fair way that lets in new users, but detects 'rude people' so that their negativity can be filtered out. It's the most challenging problem in social media today, I think, because there are so many jerks out there making life miserable for the 'good people'. A workable approach may be using Facebook logins, so that people can't as easily hide behind anonymity, but then again I hate forcing users to be on Facebook just to use some other thing. Perhaps there is a business model here (business to be made), in a company that can validate that this is a 'real' person, eliminate anonymity, and perhaps be able to 'shame people into being nice online'. So that aspect of it of course comes down to how to verify true identity online.
