Online production communities are increasingly important, creating commercially valuable software (e.g., Linux), generating scientific data (e.g., galaxyzoo.org) and building history's largest encyclopedia (Wikipedia). Motivating and coordinating the volunteers who do this work is a serious problem for many communities. This talk will review empirical research, primarily based on data from Wikipedia, that examines some of the interpersonal and managerial tactics that online production communities use to socialize new community members, to coordinate the work of volunteers and to motivate them. Our research indicates, for example, that broad-based participation is primarily valuable when a subset of the volunteers does the lion's share of the work, but is less valuable when work is distributed more evenly among them. It suggests that group goals help both motivate and socialize participants. It identifies the types of interactions between new community members and old-timers that foster commitment and continued participation. The talk will also review the CrowdForge system for coordinating the micro-contributions of Amazon Mechanical Turk workers, so that they can accomplish complex and highly interdependent projects.
