Some online communities find it difficult to integrate new members, even though incumbent members bear newcomers no apparent ill will. Using an agent-based model, we show how an exclusionary outcome might be simply the result of members entertaining a moderate preference for interacting with those who are already their friends. This echoes, in an online context, Thomas Schelling's famous segregation model. We then show that online community management practices are effective at mitigating this exclusionary dynamics. Finally, we introduce a capacity constraint to community management, and compare alternative criteria for allocating that capacity.
