This document discusses building the right online consumer community platforms. It begins with an overview of the research background and intent, which is to take a bottom-up approach understanding how individuals form communities from sociology and how producers relate to consumers from marketing. The document then outlines several research questions about user personas in online communities, gaps that cause users to leave, and the lifecycle and drop rates of users. The vision of the research is to facilitate online communities of practice that minimize costs while maximizing trust, reputation, and fun.
