Adam Greenfield, author of Everyware: The dawning age of ubiquitous computing (2006), Urban Computing and Its Discontents (2007) and the forthcoming The City Is Here For You To Use, is managing director of Urbanscale, a New York City-based design practice. He’s also been a bike messenger, a busboy, a medic at the Berkeley Free Clinic, owner of an indie coffeehouse, and a Psychological Operations sergeant in the US Army’s Special Operations Command. Go figure.
