In the time since the dotcom boom, the magnitude of Metcalfe's Law has been argued.
Last I heard, the argument was that the effect for social networking was closer to nlogn than n^2. If true, then quadrupling in size may increase the value by some number of percentage points instead of an order of magnitude.

Which means 'big enough' may not be that big.
