Quora is extremely useful. It eliminates a lot of my visits to about.com style websites and replaces them with structured q&a. It also adds a layer of transparency (you can see who has answered a question, their 'credentials') and get a feel for who to trust. It's quick and the answers to any questions so far have been insightful. I fail to see how structuring all q&a dispersed over the web to a centralised site is a bad thing? In addition Quora facilitates learning over time for topics and even individual questions I am interested. I absolutely love the follow topic & question features, i've learned a lot about topics I am passionate about using them. Information I probably would never have been able to find in any other way prior to Quora.
