  • Apr 23, 09

    We invite you to submit a proposal for the 15th Sloan-C International Conference on Online Learning: “The Power of Online Learning: Opportunities for Tomorrow.” The conference strongly encourages proposals that reflect the implications for the field of specific e-learning experience and practices. Proposals that address blended learning, issues of diversity, international applications of online learning, open educational resources and/or social networking are especially encouraged. Last year’s conference attracted over 1100 participants to more than 180 presentations, as well as exhibits, pre-conference workshops, keynote and plenary addresses, and a variety of other special events.

    Power of the few vs. wisdom of the crowd: Wikipedia and the rise of the bourgeoisie

    Kittur, A.; Chi, E. H.; Pendleton, B. A.; Suh, B.; Mytkowicz, T. Power of the few vs. wisdom of the crowd: Wikipedia and the rise of the bourgeoisie. Alt.CHI at CHI 2007; 2007 April 28 - May 3; San Jose, CA.

    Wikipedia has been a resounding success story as a collaborative system with a low cost of online participation. However, it is an open question whether the success of Wikipedia results from a “wisdom of crowds” type of effect in which a large number of people each make a small number of edits, or whether it is driven by a core group of “elite” users who do the lion’s share of the work. In this study we examined how the influence of “elite” vs. “common” users changed over time in Wikipedia. The results suggest that although Wikipedia was driven by the influence of “elite” users early on, more recently there has been a dramatic shift in workload to the “common” user. We also show the same shift in del.icio.us, a very different type of social collaborative knowledge system. We discuss how these results mirror the dynamics found in more traditional social collectives, and how they can influence the design of new collaborative knowledge systems.

    • If you address a broad issue from an angle that no one has taken before, or if you narrow your gaze to a small, precise facet of it, your site will immediately stand out by offering something that can’t be found anywhere else.

      • brilliant and subtle points, very strong start

    • who makes a B+ average, spends three hours a day at the computer and two watching TV, and who would enjoy playing massively multiplayer online role playing games (MMORPGs) if he had the money to spend on monthly subscriptions. To put it simply, you should be able to open a phone book and point to the one person who is your “ideal user.”
