Two photos from the OccupyGeziPics Tumblr show the "people's bulldozer" in action -- apparently a mechanical digger commandeered off a building site by protesters in Besiktas (one of my Twitter followers reports a rumor that it was a youth gang, and not portesters, though of course, youth gangs may be protesting too), and used to attack police barricades.
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.
