If you're tired of hearing the word "blogosphere" (which was kind of fun for a month or two in 2001) then this is the t-shirt for you: Samuel L Jackson in his Pulp Fiction persona, pointing a gun at the world and saying, "Say blogosphere again!"

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.
