A British Publisher, Penguin, launched a wiki on Thursday, and invited the world to come help write a book. A very good idea, if I do say so myself.
I'm interested to see how this turns out. My attempt brought only a handful of people in, but this looks like a much larger scale.
However it turns out, we'll still beat them to the punch. The first fiction wiki book, Bullies in the Headlights, will be out in April. Available at finer bookstores everywhere. Or at least in book stores that carry books about chicken armpits.
