Welcome back to the blogosphere, Sim. An excerpt from Sim's post on the Metcalfe's Law debate this week (read the full post for his insightful analysis):
The industry is at it again–trying to figure out what to make of Metcalfe’s Law. This time it’s IEEE Spectrum with a controversially titled “Metcalfe’s Law is Wrong”. The main thrust of the argument is that the value of a network grows O(nlogn) as opposed to O(n2). Unfortunately, the authors’ O(nlogn) suggeston is no more accurate or insightful than the original proposal.
