"We're starting Round 2 next month (in essence, starting over again at letter A to further define the world). Notes about the announcement here, as well as links to the timeline, characters, and ASCII map." Link (Thanks, Morbus!)
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.
