After launching three communities over the past two years, here's what I've learned about the critical first 100 members:
- Seed the content yourself. Nobody wants to post in an empty forum. Write 10–15 quality topics across different spaces before inviting anyone.
- Personal invitations beat mass emails. Send individual messages to people you know will contribute.
- Respond to everything. For the first month, reply to every single post. People come back when they feel heard.
- Celebrate first-time posters. A simple "Great first post, welcome!" goes a long way.
The goal isn't growth — it's establishing the culture. Get the first 100 right and the next 1,000 takes care of itself.
