“Teach the People is a Facebook application that provides a platform for online education. The application lets anyone with specific subject knowledge or a useful skill set share it by setting up a Teach the People learning communities with 1gig of free storage. The learning communities provide educators and students with all the standard learning management system tools that are standard on existing systems (Blackboard, Moodle), and some not so standard like video chat and VOIP.”
It will be interesting to see how this develops. There is some discussion of certifying teachers and such.
