GAM3R 7H30RY 1.1 is a networked book in progress by McKenzie Wark. It is hosted by The Institute for the Future of the Book as a “thinking out loud” project. They have an interesting interface for creating a structured book (chapters with paragraphs as cards). There is a syndicated version, search, comment area and documentation on the interface. I’m not sure why they didn’t use a wiki with plug ins and will have to think about what is missing from wikis other than a stack of cards look.
