The value of a telecommunications

network is proportional to the square

of the number of connected users of the system (n2).—Robert Metcalfe, c. 1980 (attributed by George Gilder in 1993)

“[E]ven Metcalfe's law understates the value

created by a group-forming network [GFN] as

it grows. […] [T]he value of a GFN increases exponentially, in proportion to 2n.”—David P. Reed, "The Law of the Pack" (Harvard Business Review, Feb. 2001,)
