Video: Nicholas Christakis Discusses The Hidden Influence of Social Networks

One of the best talks at last year’s TED talk was Nicholas Christakis’ speech on “The Hidden Influence of Social Networks”. Nicholas talks about the importance of social relationships and how human emotions balloon out through social networks and affect the world around them. He starts with a fascinating story about a woman suffering from illness, and how it affected the world around her by touching a huge variety of points on her ‘social network’.
