Details from fiction, cataloged and connected to other books and the real world. Fascinating idea. Signed up, looking forward to the invite. This is something that Wikipedia could have done. I suppose it does do this as a casual side effect, but SD is doing it explicitly. My major question (as usual) is how are they going to make money. Maybe that will be clear when I get an account. I'm assuming it will be through affiliation or even direct sales.
