Metcalfe, ReedMetcalfe, ReedSee Reed’s stuff on http://www.reed.com /gfn and in HBR

Metcalfe: the total value of a communication network grows with the square of the number of devices or people it connects. Reed: While many kinds of value grow proportionally to network size and some grow proportionally to the square of network size, some network structures scale even faster. Networks that support the construction of communicating groups create value that scales exponentially with network size

A dramatic shift of the Internet landscape away from exaggerated focus on the WWW.

Peer-to-peer will permeate the enterprise and consumer applications. P2P concentrates on distributed applications and "edge computing."
