Pretty good piece on building community:
1. The community is in control
2. Be the best electronic version of yourself
3. Listen more than you talk
4. Keep it really interesting
5. Monitor and contribute daily
6. Don’t let questions or comments go unanswered for more than 24 hours
7. If you don’t genuinely care, don’t do it
I would like to add that the control issue is crucial. You have to be willing to go where the community leads you. Otherwise it’s just another marketing campaign.
