Although heterogeneity in consumption communities is pervasive, there is little understanding of its impact on communities. This study shows how heterogeneous communities operate and interact with the marketplace. Specifically, the authors draw on actor-network theory, conceptualizing community as a network of heterogeneous actors (i.e., individuals, institutions, and resources), and examine the interplay of these actors in a mainstream activity-based consumption community -the distance running community. Findings, derived from a multimethod investigation, show that communities can preserve continuity even when heterogeneity operates as a destabilizing force. Continuity preserves when community members depend on each other for social and economic resources: a dependency that promotes the use of frame alignment practices. These practices enable the community to (re)stabilize, reproduce, and reform over time. The authors also highlight the overlapping roles of consumers and producers and develop a dimensional characterization of communities that helps bridge prior research on brand communities, consumption subcultures, and consumer tribes.Bryan is a serious runner and a member of the distance running consumption community. He is sponsored by a major athletic brand and is integral to his local running community. In addition to running competitively for almost 30 years, he is also a coach who evangelizes the benefits of running to novices and recruits and is proud of how community members interact with and support each other, regardless of their speed or how much they run. At the same time, he struggles with the participatory nature of the sport, longing for the "good old days" when only a competitive mentality prevailed. B ryan embodies the complexities and paradoxes of a strong, heterogeneous, activity-based consumption community that is able to align the differences between members. Over the past three decades, Bryan has witnessed a radical transformation of the running community from a small, competitive, tight-knit, male-dominated group to a mainstream, popular activity-based consumption community with mass participation. As outlined in appendix A, throughout these 30 years, heterogeneity has emerged in terms of the actors present within the community, the roles they play, and the resources they use and exchange. The purpose of this study is to enhance understandings of how complex heterogeneous communities manifest and interact Accetta and Paul Connell for assistance recruiting informants.
