Reed's Law states that the number of potential subgroups within a network grows exponentially based on the number of participants, according to the formula 2^n - n - 1, where n is the number of participants. The document also discusses Sarnoff's Law, which asserts that a network's value grows linearly with the number of viewers, and Metcalfe's Law, which claims a network's value grows with the square of the number of nodes. The document ponders how these laws impact the demand curve for networks and their long-term growth.

Editor's Notes
- Reed’s Law or Group Forming Network Theory as Dr David P Reed* originally and rather modestly called it, is the mathematical explanation for the power of the network. It’s breathtakingly simple, easy to understand and enormously enlightening. I hope to explain it a little and add some more recent understandings of the collaborative power of networks which I hope will make sense of and give context to the exponential.
