Cyberspace has introduced new and intriguing means for knowledge sharing as well as new structures of mediated knowledge-building communities. Considering the various forms of online communities, it should be difficult to overstate the significance of Wikipedia as a landmark in building communal knowledge repositories. Wikipedia is an online collaboratively written encyclopedia. It has unique aspects of users' involvement in the production of content and its function as a community. In less than five years of existence, Wikipedia has acquired both avid advocates and ardent adversaries. Although there have been some public and academic debates about the quality of its content, as the rapid growth of its articles and numbers of active users (Wikipedians) continues, most people agree that at least the English version of Wikipedia is approaching critical mass where substantial content disasters should become rare. Wikipedia's existence and success rely on users' inputs. Our chapter focuses on Wikipedians' incentives for contributing to Wikipedia. The popular observation is that Wikipedia only works in practice. In theory, it can never work. How does Wikipedia mobilize the levels of participation that make it “work in practice”? Wikipedia's growth, from the time of its foundation in 2001, has been impressive in all conceivable dimensions. Expansion metrics have accelerated in terms of volume, numbers of articles, visitors, and percentage of contributors. There are, by the time of this writing, 250 language editions of Wikipedia. The English-language version is the largest. It contains more than two million articles.
