IntroductionMoving from individuals to social roles simplifies complex social structures. Behavioral data identifies important social roles in online communities. Corresponding social network structures are characteristic of individuals playing specific social roles in computer-mediated interaction spaces.

Our research shows that technical support, social support, and political discussion spaces are habitats in which specific stable behaviors, “social roles”, occur. The following are several facets of behavior that illustrate key social roles in these computer-mediated collective action systems.
