In Daniel Suarez' books Daemon and Freedom (TM), the Darknet (aka D-Space) is basically a network of technophiles who rate each other depending on their actions (albeit in real life), which affects their overall reputation rating. Processes are automated and decisions made by the community based on voting. The way the Stack Exchange websites work remind me of this (granted there are major differences), kind of an eerie similarity, for anyone who knows what the book is about.
Is that where Stack Exchange got the idea of an overall reputation rating based on summing the outcomes of votes for individual actions? Or from a common ancestor? Where did the idea come from?
