Social production communities, like Wikipedia, are changing the way the world produces and shares information. However, these communities face important challenges, including attracting new members, socializing those members, keeping them actively participating, and managing conflict between members. Taken together, the effectiveness of a community at meeting these challenges is a measure of its health. Our long-term goal is to develop general measures for community health that can help the designers of any community react early and rapidly to emerging problems. In this talk we will look at a series of studies that evaluate specific aspects of community health, using Wikipedia as an example. We will discuss the signs that Wikipedia is a healthy and successful community -- and also look at some early warning signs of problems in Wikipedia that may need to be addressed soon.
