Welser, Howard T., Cosley, Dan, Kossinets, Gueorgi, Lin, Austin, Dokshin, Fedor, Gay, Geri and Smith, Marc (2011): Finding social roles in Wikipedia. In: Proceedings of the 2011 iConference 2011. pp. 122-129.

This paper investigates some of the social roles people play in the online community of Wikipedia. We start from qualitative comments posted on community oriented pages, wiki project memberships, and user talk pages in order to identify a sample of editors who represent four key roles: substantive experts, technical editors, vandal fighters, and social networkers. Patterns in edit histories and egocentric network visualizations suggest potential "structural signatures" that could be used as quantitative indicators of role adoption. Using simple metrics based on edit histories we compare two samples of Wikipedians: a collection of long term dedicated editors, and a cohort of editors from a one month window of new arrivals. According to these metrics, we find that the proportions of editor types in the new cohort are similar those observed in the sample of dedicated contributors. The number of new editors playing helpful roles in a single month's cohort nearly equal the number found in the dedicated sample. This suggests that informal socialization has the potential provide sufficient role related labor despite growth and change in Wikipedia. These results are preliminary, and we describe several ways that the method can be improved, including the expansion and refinement of role signatures and identification of other important social roles.

Underwood, Patrick and Welser, Howard T. (2011): 'The internet is here': emergent coordination and innovation of protest forms in digital culture. In: Proceedings of the 2011 iConference 2011. pp. 304-311.

The series of protests against the Church of Scientology known as "Project Chanology" marks the emergence of an important form of contemporary protest movement defined by networked internal structures and pervasive memetic culture. Such a protest movement is highly dynamic -- rapidly adapting to changing challenges and contextual settings. This cultural innovation is made possible by the increasing digital mediation of social life. In the following analysis, we trace the unique structural contours of Chanology, investigate how participants leveraged a unique internal structure and the memetic environment of the internet to grow, and conclude with an explanation of why the novel modes of protest used in Chanology contributed to its success and why these forms of protest are likely to proliferate in an increasingly digitally mediated environment. From a theoretical standpoint, Project Chanology both affirms and challenges conventional conceptions of social movements. The utility of Chwe's network analytical approach to the problems of coordination in social movements is also demonstrated.
