Starting a Co-op can be a very similar experience to starting an open source project because they are centered around the concept of people taking action and solving their own problems. Projects like these live or die by the people that volunteer their time, so it is vital to foster a strong community. This can be done by having a clear definition of the project’s cause, controlling toxic opinions and members, thanking contributors, and informing and empowering volunteers. These lessons from launching a successful Co-op can benefit any open source community.
