4.74 Degrees of Separation
This story in the New York Times summarizes a recently published study about interconnectedness on Facebook.
A computational analysis of the 721 million worldwide Facebook users shows that the average distance between two people is about 4.74 “friends”. Roughly speaking, given anyone in the world on Facebook, a friend of your friend is likely to be friends with a friend of their friend.
An amazing result! And a cool application of graph and network theory. Now the questions becomes “What can we do with this knowledge?”
