Have you made one? Link to it in the comments below.
(Thanks, Jake and Rob!)
Update: The posters you folks are posting in the comments are brilliant -- just check out this one, from Lex10.
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.
