From @LASTEXITshirts, an unattributed "commercial side of Tatooine" image, that made me guffaw. If you know who the creator is, please leave it in the comments!
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.
