Three and a Half Degrees of Separation (via Facebook Research)

Starting with the original Milgram research in the 1960’s to the Dodds, Muhamad & Watts (2003) paper in Science, the exploration of the social distance between individuals in society has been a topic of interest to many scientists.  This new release from researchers at Facebook highlights that social distance is indeed declining.  For those who might be interested – I detail in these slides and these slides the history of the small world research.
