This is a really interesting book. But, boy, there must not be any introverts at Google. I'm not sure I agree with all of their thinking as far as it always being better for the company to have an employee who does their best thinking in the company of others, and also hangs out with others mostly in their spare time. There have been so many creative high achievers over the years who work best alone. If you are trying to build a culture that incorporates the best people, surely that would include some of those more self-contained individuals also. I'm not sure that I necessarily buy it that a person who likes quiet to work, or who tends to get tasks done himself rather than reaching out to others, is necessarily an un-innovative control freak. It's still a fascinating look into their culture, though.
