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.
