The document discusses the dynamics of Wikipedia editing, including a logistic growth model to analyze editor activities and population changes. It highlights a shift from exponential to logistic growth and examines factors like edit classes, revert resistance, and admin changes. Key takeaways suggest that Wikipedia serves as a unique experiment in knowledge co-creation, with implications for community structure and editing behavior.

Editing activity changing Moved from exponential growth to logistic growth Population dynamic changing Revert resistance different for lower class editors Middle class being squeezed Pyramid structure important? Protection measures correlate with activity
