In order to help teachers bring their classes to Second Life, Linden Lab donates accounts for each student, as well as an acre of land in the metaverse for the teacher and students to work and build on. Afterward, anyone wishing to stay a member can do so at half price.Link
To date, in addition to Delwiche and Beamish, professors from San Francisco State University, the Rochester Institute of Technology and Vassar College have used Second Life in their courses.
I write books. My latest is a YA science fiction novel called Homeland (it's the sequel to Little Brother). More books: Rapture of the Nerds (a novel, with Charlie Stross); With a Little Help (short stories); and The Great Big Beautiful Tomorrow (novella and nonfic). I speak all over the place and I tweet and tumble, too.
