Our lives are increasingly mediated by computers and data – a shift that is becoming more and more natural to us. From Data.gov to real-time municipal bus information, data in many forms from many sources is being made available and recombined in ways we could not have anticipated just ten years ago, when everyone used the phone book, and when restaurant and movie reviewers numbered in the tens not the tens of thousands.
