Running groups people stay in: onboarding, moderation policy, ambassador programs, event rhythm, and the metrics that show a community is alive.
Platform choice is a data-model decision before it is a features decision — ownership, search, events and export rights determine whether a community can ever migrate.
Ambassador programs convert a community's most invested members into a working extension of the team — if selection, motivation and boundaries are designed deliberately.
Community-led growth generates acquisition, retention and support economics that paid channels cannot — but only for products members can genuinely help each other use.
A moderation policy that survives contact with real conflict needs published rules, a defined escalation ladder, transparent enforcement and a consistent violation ledger.
An audience is measured by reach; a community is measured by relationships between members — and the two require completely different KPIs.
Community health shows up in three measurable layers — active cores, member retention and network connectedness — not in aggregate post volume.
