Nivi has an interesting post comparing Reed’s Law & Metcalfe’s Law, he discusses an entire range of Sarnoff , Odlyzko and Haque‘s Law. It would be interesting to check out Umair’s response to it (especially Dunbar number). And yes of course this post leads to a Nivi’s Law :-), leaving no hole unplugged so that a new network law can be created 🙂
