Harper Reed is an American technologist, known for being the CTO behind Obama's 2012 re-election campaign, for his involvement in pioneering online crowdsourcing company Threadless, his hairstyle, and many other weird and wonderful projects he gets involved in. Severin met Harper at MIT’s media lab in Berlin, in August last year. Being a fan of Harper’s work for many years, he took the opportunity to ask him about what Harper calls his life waves: periods in his career when he quit everything and said yes to any new opportunity that came his way. Like this interview. Or building one of the first crowdsourcing communities on the internet. Using social technology to get a president elected. Or predicting the future for a living. All this, and more, including sirens and pan flute recitals, in episode #16 of The Community Podcast.
