Update: RBP sez, "Sao Paulo and Rio de Janeiro have similar book-vending machines on underground stations. Sao Paulo also has a public library in one station, where people can register and borrow books for free, including a few in Braille." Also: book-vending machines are on the streets of Barcelona, apparently.
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.
