This document discusses open collaboration and provides three key lessons from libre software projects that can be applied to understanding Wikipedia. It summarizes research analyzing Wikipedia using a tool called WikiXRay. The research found that (1) the distribution of contributions follows a Pareto distribution, (2) the monthly effort distribution has remained constant over time, and (3) featured articles tend to be older and involve more editors than non-featured articles. The document proposes future areas of research involving change patterns, contribution types, and traffic.
![The ¡°paradox¡± of open collaboration
¡°Wikipedia is the best thing ever. Anyone in the world can
write anything they want about any subject, so you know
you are getting the best possible information.¡±.
