Communal aspects of digital culture run deep and wide. Wikipedia is just one remarkable example of an emerging collectivism—and not just Wikipedia but wikiness at large. Ward Cunningham, who invented the first collaborative Web page in 1994, tracks nearly 150 wiki engines today, each powering myriad sites. Wetpaint, launched just three years ago, hosts more than 1 million communal efforts. Widespread adoption of the share-friendly Creative Commons alternative copyright license and the rise of ubiquitous file-sharing are two more steps in this shift. Mushrooming collaborative sites like Digg, StumbleUpon, the Hype Machine, and Twine have added weight to this great upheaval. Nearly every day another startup proudly heralds a new way to harness community action. These developments suggest a steady move toward a sort of socialism uniquely tuned for a networked world.
