Scale Versus Vitality
A community can grow quickly while weakening at the core, so track scale and vitality separately to avoid confusing reach with resilience. Combine member counts, activation rates, and unique contributors with depth signals such as helpful replies, mentorship, and returning participation across cohorts. Ask whether newcomers find their place, whether veterans still feel seen, and whether conversations remain constructive. Listen for qualitative echoes in surveys and interviews to ensure numbers represent lived experience. Sustainable vitality is earned, not assumed.
