In the small world experiment, it was observed that anyone in the world could reach any other person in the world in about 5.2 intermediates (thus 6-degree of separation). This observation was made more than 50 years ago. The Internet should have shortened this average path distance. Suppose with the use of Internet and online social networks, every person in the world increases their number of friends by doubling it (2x). Please estimate the new degree of separation. Explain your estimation.
