Chris Raettig, the guy who discovered KPMG's dumbass linking policy the hard way, has started wandering around London near KPMG's office with signs that read "KPMG is this way" -- linking to them again in meatspace.LinkDiscuss (Thanks, Rich!) 
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.
