Naturally, the Wikinomics site includes a wiki -- a place where readers of the book can write the missing "eleventh chapter" of the book, based on their real-world experiences with wikinomic activity.
Tapscott interviewed me and my fellow Boinger David Pescovitz, along with a lot of the people whose opinions I listen to carefully in this world. I've started looking through the book and I've found it an easy read, with good insight. It's like Benkler's Wealth of Networks, but written for a non-academic audience.
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.
