Facebook does research (they do? yes) using analytics from their social media platform. They recently tested the hypothesis that there are 6 degrees of separation between everyone on the planet. What they found was: "Each person in the world (at least among the 1.59 billion people active on Facebook) is connected to every other person by an average of three and a half other people."
What implications does this have for anthropologists thinking about community building, globalization, or human or item movements?
Or, is Facebook really trying to bring the internet.org (i.e. facebook apps) to every part of India in order to continue to lower these degrees of separation?
