I also don't understand the 80million (perhaps rich people don't know where to put their money?). But Quora is definitely not just another Q&A site. First, they have incredibly good technology. I would say that their livenode/webnode2 framework is one of the (or the) most technologically advanced web frameworks in existence. (Although now that React exists, it should be relatively easy to create something even better than what Quora has.) Also, I like their deployment process - they auto-deploy on every commit if tests run flawlessly. And their CEO is pretty smart (http://www.quora.com/Adam-DAngelo-1/What-are-some-good-stories-about-Adam-DAngelos-bad-assery?share=1 http://www.quora.com/Adam-DAngelo-1/What-are-some-good-stori...). Second, there's lot of very valuable and high quality content. I've learned a lot from Quora.
