Considering the popularity of the term "network effects" as an answer to all questions in Strategical Analysis of IT, here's a law dedicated to the enlightening concept:
"The value of the concept of network effects increases with the number of MBA students who buy in to the concept".
This, my friends, is the reason the dear professor repeats the term 25.3 (calculated using mulitple regresson after accounting for multi-collinearity and micro numerosity) times in every class, on average.
Happy networking and effecting!
