Quora’s terms of service. Clear and simple. And amazingly similar to how I think of group emailing. Nice permissioning system too.
A friend asked me a while back why Quora will succeed where Yahoo Answers failed, and I think things like this are the reason. At every touchpoint, Quora creates a safe, friendly and engaging environment in the same way that Starbucks does. And if Quora is Starbucks, Y!A is closer to the White Castle coffee pot.
