Author Seth Godin is all about change. In “Tribes,” as he has in his previous books such as “Purple Cow” and “The Dip,” he challenges the status quo with a straight-on, get-with-it kind of attitude, and you got to love him for it. His books are sweetly short, and they manage to be breezy and thought-provoking at the same time. This time out he tackles the oft-dissected concept of leadership. But he does so with a twist. He delves into the surfacing of a new kind of leader.
