Have heard of Metcalfe's law and Reed's law for the first time thanks to a @netzpolitik_feed article. Which reaffirms my believe + efforts to get #multicast routing between #Freifunk communities working. The Metalcafe's law says a network grows by value/importance proportional to the square and had a classic telephone network in mind. For multicast I think Reed's law seems more fitting, which considers all potential subgroups, with an exponential value/importance. https://en.wikipedia.org/wiki/Reed%27s_law
