For most of human history, the rules of power were clear: power was something to be seized and then jealously guarded. This "old power" was out of reach for the vast majority of people. But our ubiquitous connectivity makes possible a different kind of power. "New power" is made by many. It is open, participatory, and peer-driven. It works like a current, not a currency--and it is most forceful when it surges. The battle between old and new power is determining who governs us, how we work, and even how we think and feel.
