khan academy does so but with a definite focus on children, this feels a little more grown up. Besides, just because khan does similar things does not reduce the value potential this has. There is a lot more of a social SO type feel with Function Space whereby a user can ask questions and receive answers in an open forum. That is more hidden on khan. For those of you complaining about the login. Give it a shot, there is a fairly well thought out site behind that login and the dev has expressed his intent to make things more open. With a site like this being able to ask and comment is kinda key to it working anyways. Use your spam address on the site until you feel it's worthy of your "personal" one. But do check it out. Free and open access to knowledge and knowledgeable people needs to be done in as many places and formats as possible. I hope this goes far. O.
