The Disney Fakes blog catalogs forged Disney art for sale on eBay, painstakingly cataloging the tells and errors made by the forgers. Some are hilariously bad, others are damned subtle.
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.
