Four degrees of separation

A recent study by The University of Milan and Facebook has shown that the old adage "6 degrees of separation" that connects any two people on the planet is not true. The new study of 69 billion Facebook friendships (the largest social network study ever) shows that 92% of us are connected  by only four degrees (five hops). Take a moment and think about this ... Choose anybody, Barack Obama perhaps; it is probable that a friend of a friend of yours, knows a friend of a friends of Obama's! The researcher also shows that within the same country most pairs of people are separated by only three degrees (four hops). They'll need to rename that Kevin Bacon game.
