Smart Mobs, the best-selling book of that name by Howard Rheingold, continues the investigation launched by the best-selling book of that name, about the merger of the mobile telephone, the personal computer, and the Internet into a new medium that enables collective action in ways that were never before possible. New industries have arisen, political leaders have been deposed and elected, new cultural practices have arisen. Anyone interested in the new forms of socializing, the emergence of new kinds of cooperative enterprise in the for-profit and non-profit world, the beginning of the "age of sentient things" in which trillions of smartifacts will permeate manufactured objects with computational capabilities, the potential of grid computing, the novel ways in which people put mobile telephones to use, follows the Smart Mobs team of international bloggers from USA, Australia, Netherlands, Brazil, and Switzerland as they focus on daily developments at the intersection of technology, social practice, and enterprise.
