Dopplr Offsetr was a piece of software satire developed with the Dopplr API. Dopplr, a social travel network, reported friends’ trips, and in a way illuminated a kind of social hierarchy in which frequency of travel was paramount in importance. Offsetr played with this idea by creating a set of leaderboards for your social network, but framed the scores as the aggregate carbon footprint for each individual. The software was written about on O’Reilly Radar, among other places around the web.
