What value do we add that would make users want to post their questions on our site, as opposed to reddit.com, quora.com, answers.com, and answers.yahoo.com? I realize that those sites are general purpose, and have a different mission, but they seem to benefit more from their parent organizations than we do from StackExchange.
Does anyone have any suggestions for what it is about our site that means people should come here for the answers to their history questions?
