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.

In the first adoption horizon we find mobiles and cloud computing, both of which are already well established on many campuses — and still more organizations have plans in place to make use of these technologies in the coming months. Institutions at the leading edge of technology adoption are also already applying the two clusters of technologies we have placed on the mid-term horizon, geo-everything and the personal web. All four topics on the first two horizons are already in common use in other sectors, including entertainment, commerce, and the world of work. The two technologies placed on the far-term horizon, semantic-aware applications and smart objects, are not yet commonly found in an educational context, although research is being conducted in both areas and the rate of development seems to indicate that these topics are well worth watching.

Each profiled technology is described in detail in the body of the report, including a discussion of what it is and why it is relevant to teaching, learning, research, and creative expression. Specific examples are listed there for each of the six topics, consistent with the level of adoption at the time the report was written (December 2008). Taken as a set, our research indicates that all six of these technologies will significantly impact the choices of learning-focused organizations within the next five years.

Online retailers Amazon and Abebooks have both shown an interest in the sites, making substantial investments in them. So far publishers have done little to try to exploit the sites, though that may be about to change. The most popular of these sites, LibraryThing.com, has just announced a program by which publishers can supply some of its members with ARCs of forthcoming books.

Serving as virtual libraries, sites like LibraryThing, Shelfari.com and GoodReads.com give readers an online place to meet, discuss and—most significantly for publishers—list all the books in their life: ones they own, ones they’ve read and ones they want to read. LibraryThing.com has more than 200,000 users, each with an average of 70 books on his or her shelf, giving book publishers a highly useful market research tool.
