Open source book

For a while I’ve thought it would be cool to set up an open source book project. Tools like wiki make it pretty easy. Writing an open source book would be fun. A lot of us may never be able to author a book, but we’re more than able to contribute something as a collaborators, and edit what others have written. It takes away the intimidation factor and lets everyone in on the fun. There are also lots of drawbacks. It wouldn’t be a conventional book, nobody would own it, and it could flop. It’s hard to say what the end result would look like, which may or may not be good. What do you think? Is it worth a try? Or is the nuttiest idea so far this year?
