I didn't think this question would fit in any of the other forums, hopefully this is the right place... I'm not sure how many other people on this forum are familiar with StackOverflow - it's basically a question-and-answer site for computer programming where members can rate each others' questions and answers. Anyway, for quite a while, since even before I joined PF, I've been thinking that the format of the site might work pretty well for physics Q&As as well. (I can understand the concern that a lot of people who may not know much about physics would be involved in the rating process, but the model works well for programming, so I figure it's at least worth a try for physics) Now that the people behind StackOverflow are planning to make their system available for other topics, I'd like to start one for physics, but I want to gauge whether it's going to be worthwhile first. So the question is, does anyone know whether there's an already-established project applying the StackOverflow model to physics? And if not, do you think there'd be enough interest to make it worth starting one?
