There are 721 million Facebook users i.e more than one-tenth of world's population. Researchers at university of Milan developed and used an algorithm to calculate the average distance between two people by computing a vast number of sample paths among Facebook users. The result showed up that an arbitrary distance between two is just 4.74. In US, it is 4.37.
Matthew O. Jackson, an economist at Stanford who studies social networks, raised questions about the bias built into a study based on random samples. He said the study confirmed Facebook’s success in being where millions of people communicate. “It’s more evidence that they’ve been enormously successful at connecting a large number of people very well,” he said, as per NYT.
“These social network tools provide individuals with tremendous reach,” said Dr. Horvitz, the Microsoft researcher. “People can share ideas with only a few jumps to a large portion of the world’s population and with even fewer steps to the entire population of a nation.” according to NYT.
