Ideological Segregation among Online Collaborators: Evidence from Wikipedians English October 2016 Do online communities segregate into separate conversations when contributing to contestable knowledge involving controversial, subjective, and unverifiable topics? We analyze the contributors of biased and slanted content in Wikipedia articles about U.S. politics, and focus on two research questions: (1) Do contributors display tendencies to contribute to sites with similar or opposing biases and slants? (2) Do contributors learn from experience with extreme or neutral content, and does that experience change the slant and bias of their contributions over time? The findings show enormous heterogeneity in contributors and their contributions, and, importantly, an overall trend towards less segregated conversations. A higher percentage of contributors have a tendency to edit articles with the opposite slant than articles with similar slant. We also observe the slant of contributions becoming more neutral over time, not more extreme, and, remarkably, the largest such declines are found with contributors who interact with articles that have greater biases. We also find some significant differences between Republicans and Democrats. 0 0
The range of linus' law IEEE Micro English 2012 Shane Greenstein discusses how Linus' Law works in case of wikipedia. Linus' Law is infeasible without the web. That much is obvious. The diffusion of the web reduced the costs of assembling the attention of many reviewers, making it feasible to have a crowd focus on the same text. Articles vary in the number of contributions per day, week, or month, so some have accumulated many contributions over time while others have not. Articles also vary in the type of contributors they attract, and in the outlook of those contributors. Moreover, the organization eventually adopted policies for entries for controversial living persons, allowing only administrators to revise the entries. Linus' Law depends on some economic conditions and quite a few supplements. Eyeballs may be cheap to assemble, but it works better at Wikipedia when objective information is inexpensive to find, or when additional subjective information is cheap to add. It also works better when the cost of verification is low. 0 0

Learning from Wikipedia
Case Collection at the Kellogg School of Management. Case Collection.aspx 2009 In 2009 Wikia was the Internet’s largest for-profit provider of hosted open-source wikis, with over a million daily users. After five years of existence, the organization had supported a wide range of exploratory activities, experiencing both success and failure. With approximately $3 million of cash on hand, Wikia turned cash flow positive in 2009, with revenues of approximately $4.5 million, affording it time and flexibility to try new things. Some of the company’s employees and investors suggested that Wikia should attempt to expand and market itself more aggressively, but which strategic direction should receive priority? The case presents many of the issues and tradeoffs facing CEO Gil Penchina as he formulates these priorities. 0 0
Wagging Wikipedia's long tail Economics

IEEE Micro English 2007 In 2005, Wikipedia surpassed Encarta as the Internet's most popular reference site. Wikipedia calls itself the free encyclopedia that anyone can edit and it has grown rapidly since its founding in 2001. As an educator and parent, Greenstein finds himself struggling to come to terms with the economics of Wikipedia, which have shaped a resource that is at times very good, but occasionally poor. The inconsistency is a result of Wikipedia's long tail, a characteristic that requires some explanation. And thereby hangs a tale. 0 0
