If you stopped reading right here in this book, you would have absorbed nearly all of the high-level strategic thinking that is commonly referenced for network effects. I covered a bit of history, defined a few bits of jargon, threw in a couple of case studies where a big network wallops a small one, a definition for Metcalfe’s Law, and some strategic implications. And yet it is not even close to enough for those in the industry who seek to create, scale, and compete using this powerful force.
