Update: Joel "Deadpan" Johnson writes, "The recursive stuff on that post was just a joke. There is only one layer of abstraction; you swing the sword and your character swings his, end of story. I'm obviously TOO FUNNY for my own good."
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.
