It's interesting that StackOverflow is mentioned. They make no secret of the fact that they set out to kill Experts Exchange - they recognised early on that locking up content was going to hurt their longterm prospects. They also recognized that traditional online advertising wasn't going to work for their kind of content and pursued other monetization strategies to supplement it. Which is why I'm surprised that the founders of Quora continue to beat down the same tired path that has killed so many startups before them. Do they seriously believe that what worked for their previous company is going to work for them at Quora. For a platform that's all about discussing big ideas they seem surprisingly bereft of them on the business side.
