The School of Everything is an addition to marketplaces like Foodzie, Etsy and Threadless that offers not homemade products, but education. The School of Everything is a place where tutors and teachers can share their knowledge about, well, everything, and where pupils can find professors.
This education marketplace works just like other types of marketplaces. Teachers and tutors can set their own rates and select their own subject matter. They can work for free or barter with another teacher in exchange for their services. The School of Everything is open to anyone in the world, and so long as subject matter is legal, it's similarly unrestricted.
