Update: Xopl adds, "Rage Against the Machine had a scheduled legal concert in the Target Center in downtown Minneapolis tonight. Police and media where sitting and waiting outside during the whole concert in heavy numbers just waiting for something to happen when the show got out. The police got what they wanted. Police pepper spraying going on right now." Twitter 1, Twitter 2

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.
