Social Capital (Shirky)

Social capital, in Shirky's usage, is the web of trust, reciprocity, and shared norms that makes sustained collective action possible. The concept is borrowed from Robert Putnam's work on civic engagement, but Shirky's contribution is to show how participatory platforms build it as a byproduct of the participatory process. Wikipedia editors who work on the same articles over months develop relationships of trust and mutual recognition. Open-source contributors who review each other's code develop respect grounded in demonstrated competence. The social capital is not an additional feature of participation; it is woven into the participatory process itself. The accumulation is automatic because participation is inherently social — you cannot contribute to a shared project without interacting, however indirectly, with the others contributing to the same project.
