We study the process of collecting, processing, validating, and distributing information in self-organized complex social systems based on data from, e.g., the online encyclopedia Wikipedia. We correlate page access statistics, page edit statistics, and article network structure (defined by links) to characterize the lifecycle of relevant pieces of information. Results are also compared regarding regional contexts and different languages. Focusing on extreme events we analyze scaling behavior and investigate current limitations that could be eliminated by optimizing of the communication processes.
