Here's the world's shortest, fairest, and simplest licence agreement: "Don't violate copyright law." If I had my way, every digital download from the music in the iTunes and Amazon MP3 store, to the ebooks for the Kindle and Sony Reader, to the games for your Xbox, would bear this – and only this – as its licence agreement.You shouldn't have to sell your soul just to download some music
"Don't violate copyright law" has a lot going for it, but the best thing about it is what it signals to the purchaser, namely: "You are not about to get screwed."
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.
