Many of the problems of the copyright system come from copyright in the wrong hands. When copyrights get accumulated into large stockpiles, bad things often happen, things that often aren't in the interests of authors.Link (Thanks, Tim!)
Too often authors and other creators end up giving away their copyrights when they don't need to. The point of our site, keepyourcopyrights.org, is to educate lawyers and non-lawyers on what to expect. We have collected actual contracts with dangerous language to teach people what to look out for.
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.
