Quote from the Abstract Dynamics article on Friendster: The Idiot Savant (Friendster Triumphant): "Now Metcalfe's Law actually isn't much of a law, its a conjecture that, at the moment, is pretty reasonably supported by empirical evidence. What it says is that the value of a network increases exponentially with the number of members in the network. Now Friendster's network is shockingly large. Close to 2 million accounts at the moment, and still growing fast (exponentially?). If Metcalfe's law is even close to true, the value of the Friendster network is increasing tremendously each day. And quite honestly I just don't see how any competitor is going to be able to build up a comparable network. "
