After increasing rapidly over seven years, the number of active contributors to English Wikipedia peaked in 2007 and has been in decline since. A body of evidence will be presented that suggests English Wikipedia’s pattern of growth and decline appears to be a general feature of “peer production”—the model of collaborative production that has produced millions of wikis, free/open source software projects, websites like OpenStreetMap, and more.
It will be argued that this pattern of growth, maturity, and decline is not caused by newcomers who have stopped showing up, but rather because communities have become less open to the newcomers who do arrive. A theoretical model and a range of empirical evidence will be provided that suggests why this surprising dynamic may be a rational approach to the shifting governance challenges faced by digital knowledge commons.
