Jeremy Dean is building a global community of educators who use the site in a wide range of ways. They're getting pupils to write onto the site, they're setting tasks through it, like a VLE - literally, the only limit is what you can imagine and what you trust your students to do. This link shows a range of educators and the work they're doing - you will, of course, note that they're mostly English / Language Arts teachers.
