In this episode, we continue our community series with a recent discussion that applies to many kinds of community building. Today’s topic: How do you create a platform that people not only use, but tell their friends about? One that goes beyond just being useful and actually connects deeply with the user? In this discussion, which was recorded at our Crypto Startup School in April 2020, a16z General Partner Chris Dixon talked about building communities — specifically, communities of open-source developers — with GitHub cofounder Tom Preston-Werner. They discussed how to engage early users, how to turn them into your biggest advocates, how to create superfans, and more. Today, GitHub is the leading community for open-source developers and others. They also discuss in-person communities vs. distributed communities, a topic that is very top of mind today.
