Book excerpt: “I'm Outta Here! How coworking is making the office obsolete” is a book about the people and places that make up a work place revolution. From a single space in San Francisco at the beginning of 2006, coworking has grown to over 70 spaces worldwide at the end of 2008, with more appearing almost daily. Read the book and you'll see why so many talented workers have turned their backs to the office and said, “I'm outta here!”
