Contribution Spread

Contribution Spread is a community health metric that measures the distribution of active participation across a community's member base. It moves beyond simple volume metrics (like the total number of posts or comments) to analyse who is contributing and how evenly that activity is spread. The primary purpose of this metric is to determine whether a community has broad, healthy engagement from many members or if it is heavily reliant on a small cohort of 'super-users'. A healthy spread indicates resilience and widespread value perception, while a concentrated spread can signal significant risk and potential barriers to participation.

Why it matters — Contribution Spread

Understanding the distribution of contributions is critical for diagnosing the underlying health and sustainability of a community. Relying on top-line activity numbers alone can mask serious structural weaknesses.
