When Joichi "Joi" Ito speaks, the digerati listen. The onetime college dropout and nightclub DJ has become one of the Web's leading thinkers and writers on a number of cutting-edge technologies, from online multiplayer games such as World of Warcraft to social networks. The Japanese native is also an entrepreneur, angel investor in companies such as Flickr (later acquired by Yahoo) and Six Apart, and board member at companies such as corporate collaboration firm Socialtext and blog tracker Technorati. Currently, among his seemingly endless list of activities, he's CEO of the nonprofit group Creative Commons, which helps authors, artists, and others easily mark how they'd like their work to be used online.
