實在是拿來實驗 Six degrees of separation 的好方法 XDDD



--



目前實驗結果是 想找的人大部份可以在6 degrees內找到關係 (透過5個朋友)



超過6 degrees的 也許還有網路找不出的關係存在 (長輩就沒在用無名啊~) 



找不到關係的 通常是某一方通通沒有設好友 或好友設定關閉   XD

Six degrees of separation refers to the idea that, if a person is one step away from each person he or she knows and two steps away from each person who is known by one of the people he or she knows, then everyone is an average of six "steps" away from each person on Earth.
