…only let the best people in.
This is a basic rule of building communities, people will recruit others like them.
The most intelligent, beautiful, successful, richest and annoying people will all attract and recruit people like themselves.
This has clear implications for creating a community.
When you launch a community, you should be picky. Extremely picky. Don’t try to recruit everybody. Pinpoint the exact people you want and spend all your efforts recruiting them. Don’t drop your standards, keep them high.
If you want an elite community, only let elite people in. If you want your brand’s biggest fans, only let your brand’s biggest fans join. If you want industry influencers, only let the influencers in.
