Meet Adam. He’s a mid-level engineer at a mid-level software company in a cookie-cutter California office park. He can code a handful of languages, has a penchant for computer vision and enjoys soccer and skiing. In short, Adam has little to distinguish him from legions of other programmers in the Bay Area. Except that over a couple of nights in 2011, he stopped thousands of people from sharing in $50,000, nudged the American military in a new direction, and may have changed crowdsourcing forever.

The intro’s a bit hyperbolic but it is an interesting read.
