Hm-m. I don't think we're on the same page here. The transcript of that talk includes this: In almost any comparison you can think of, if there are two competing technologies, one of which has visible benefits from network effects, and the other of which doesn't, the one with the visible benefits from network effects is the one that's going to win. This is not inherently evil; it's also not inherently good. It does have unambiguous benefits. The network effect provides the payoff which helps induce us as a society to make choices when we need to. If Skype has 20 times as many users as Google Talk or Gizmo, it's way more than 20 times as useful to, um, use it. I can't think of any economic analysis that indicates rationale choice of benefits is lemming-like. Perhaps you're mistaking me for one of those guys who camped out for 24 hours in order to buy an iPhone and two-year AT&T contract.
