"HNers belly-ache about Quora all day, but there is an incredible amount of information on there" That's an exceptionally strange dichotomy, people are annoyed BECAUSE there is useful information there, and the company is enforcing mostly unnecessary "social" aspects to access the data. If the data was useless, why would anyone care when they change their policy to something aggressively anti-privacy?
