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.

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

reddit-automation
flowkit-labs/skills
Find Reddit threads where people are genuinely asking for what you offer, then draft short, genuinely helpful replies — disclosing your affiliation honestly and naming your product only when it truly answers the question. Two moves: discovery — scan the right subreddits for real needs (recommendation asks, expressed pain, competitor mentions) and rank the few threads where you can actually help; drafting — write from real experience, respect each community's self-promo rules, and keep a human in the loop to review and post. This markets on Reddit the honest way: contribute value, disclose who you are, never astroturf. Distilled from the playbook behind doany.ai's Reddit agent. Triggers on "find reddit opportunities", "reddit marketing", "reddit automation", "reply on reddit for my product", "reddit community engagement", "reddit lead gen", or any ask to turn Reddit threads into genuine, disclosed marketing replies.
