Earlier this month I sat down with Dr. Craig Zelizer, Associate Director of the Conflict Resolution MA Program at Georgetown University and TechChange Advisor, to talk about the online professional network that he created in 2008 called the Peace and Collaborative Development Network (PCDN). PCDN has grown to over 16,000 members, 250,000 hits a month and is one of the most well respected and utilized sites in the field of peace and conflict studies. The aim of the site is “to foster dialogue and sharing of resources in international development, conflict resolution, gender mainstreaming, human rights, social entrepreneurship and related fields.” I was eager to learn about the network’s origins, successes, challenges and future plans. Highlights from our conversation are featured below.
