There are a few important ways in which network effects break down that I want to call out. First, negative network effects, or things that get worse in the network with each additional member. This is the less talked about network effect. A good example is found in cities. More people move to cities to take advantage of opportunities they afford, but this also leads to problems, like road traffic congestion or air quality, and sometimes the costs tip over to exceed the benefits.
