摘要：

Critics have declared Metcalfe's law, which states that the value of a network grows as the square of the number of its users, a gross overestimation of the network effect, but nobody has tested the law with real data. Using a generalization of the sigmoid function called the netoid, Ethernet's inventor and the law's originator models Facebook user growth over the past decade and fits his law to the associated revenue.
