New jargon: "Spim." Instant Message spam. Various startups are contracting with companies to send you AIM/MSN Messenger/ICQ messages that say things like "Hey, FAOschwartz.com is having a sale!" Discuss (Thanks, ronks!)
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.
