Book excerpt: Virtual communities are a new frontier in the digital landscape. While these spaces are only in their infancy, it will not be long before they become a part of much of the population’s daily life. Before that becomes the case, it is important that we instill guidelines and parameters to ensure that those interacting with these digital spaces feel safe within them and are able to use them to their fullest capacity. Building Power, Safety, and Trust in Virtual Communities examines how online groups help people learn and change the way they think. In this book, different people with different academic backgrounds, methods, and personal experience with virtual groups look at this question. Case studies are included to help exemplify these findings. Together, these chapters discuss how virtual communities are built in ways that thinkers, researchers, and practitioners can understand.
