In 2008, Kevin Kelly and Gary Wolf created a Web site called Quantified Self, or QS, catering to users of self-regulation technology. The QS movement is still small and heavily geeky, but already it has spread far from Silicon Valley, and devotees in cities around the world are convening—in person—to talk gadgets, share data, and encourage one another.
Interesting point: the vast majority of Quantified Self followers don't consider themselves followers. They don't meet to discuss QS. They just use a Fitbit or whatever else and interact with friends. A movement is mainstream when it doesn't depend on tight interpersonal relationships (can we say cultish behaviour?)
