Stupendous! I had a completely rockin' time a Penguicon a couple years back -- it's the perfect mix of geek passions. Plus, Whuffie's about as stable a currency as you're likely to find these days as half a petabuck of toxic debt gets de-leveraged.
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.
