Community Maturity Model

Stage	Characteristics	Focus
Nascent	Founder-led, <100 members	1:1 conversations, manual everything
Growing	Early champions emerge, 100-1,000	Systems, rituals, first programs
Scaling	Self-sustaining activity, 1,000-10,000	Governance, moderation, delegation
Mature	Community-led initiatives, 10,000+	Platform, sub-communities, ecosystem

Member Journey Stages

Stage	Goal	Key Metric
Lurker	First interaction	Post/reply count
Newcomer	Find value, connect	Retention D7
Regular	Form habits, contribute	Weekly active
Champion	Lead initiatives	Content created
Ambassador	Represent externally	Referrals, reach

The 1-9-90 Rule

In most communities:

1% create content (Creators)
9% engage with content (Contributors)
90% consume content (Lurkers)

Goal: Move people up the engagement ladder, not force everyone to create.

Community vs Audience

Dimension	Audience	Community
Direction	One to many	Many to many
Value	From creator	From each other
Ownership	Creator owns	Members co-own
Content	Creator produces	Members produce
Retention	Content-dependent	Relationship-dependent
Scalability	Linear	Network effects

Platform Comparison at a Glance

Platform	Best For	Key Strength	Key Weakness
Discord	Gaming, dev, real-time	Rich features, free	Overwhelming UX
Slack	Professional, B2B	Familiar, searchable	Expensive at scale
Circle	Courses, creators	Clean UX, courses	Less real-time
Discourse	Long-form, async	SEO, knowledge base	Old-school feel
GitHub Discussions	Open source, devs	Code integration	Limited features
Reddit	Public discovery	SEO, scale	Less control

Key Metrics Overview

Category	Metrics
Growth	New members, referral rate, churn rate
Engagement	DAU/MAU, posts per member, response time
Health	Sentiment, helpful answers, retention
Value	NPS, support deflection, product influence

Motion	Description	Best For

Anti-Patterns

Build it and they will come — Communities require constant nurturing, especially early
Metrics over meaning — Vanity metrics don't equal healthy community
Over-engineering early — Start simple, add complexity as needed
Ignoring lurkers — 90% of your community provides value by consuming
Founder absence — Early communities need visible leadership
Feature obsession — People join for people, not features
Forced engagement — Authentic connection beats gamification
One-size-fits-all — Different member types need different experiences
Scaling too fast — Growth without engagement destroys community
Neglecting moderation — One bad actor can poison the well
