Influence and Roles in Social Networks

DanCo had the good fortune to work with a number of folks in Communication (Geri Gay, Xia Ling, and Connie Yuan), Sociology (Ted Welser, Gueorgi Kossinets), and Computer Science (David Crandall, Dan Huttenlocher, Jon Kleinberg, Sid Suri) on a series of problems around understanding how social networks might influence behavior in Wikipedia. For instance, how much do influential figures help explain the spread of tools, and how much do the people you talk to help shape the articles that you work on?
