"However, it seems that you can do something similar with online document sharing site Scribd: DRMed PDF files can be downloaded in plain text and several other formats, and there's even an unencumbered PDF download option!" Link (Thanks, Andreas!)
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.
