FreeCulture.org : This is the "National Organization" as we refer to it. It's basically a good place to see who is doing what else in the Free Culture world. I'm on the board, but it's just a title -- local chapters are really where the action is at.Link (Thanks, Fred!)
Free Culture Chapters Around the World : See all the other schools where chapters are located. FreeCulture.org has a discussion e-mail list, and an announcements list.If you're looking to debate and talk about Free Culture and these issues on campus, the discussion list is probably the best place in the world for that. Sign up for the announcements list as it's a good place to learn about Free Culture news before it hits the media. Creative Commons, EFF, The Free Software Foundation, and Public Knowledge are the big institutional players in our world, and many people working in the free culture movement either work with them, for them, or around them. Check out their sites for more information about what they do.
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.
