Some great thoughts on network effects from Anu Hariharan on Twitter:
  • Often misunderstood - Network Effects is not the same as scale
  • One simple way to test for that is ask this question - what is the “barrier to exit” for the user?
  • If the barrier to exit for the user is low, then there is no network effect. This implies it is easy for users to switch from your service
  • Ride sharing services (Uber, Lyft) don’t have a network effect (in other words demand side economies of scale). Users often switch apps if it takes longer than 5 mins ETA or if there is surge pricing on one
  • However ride sharing does have supply side economies of scale and therefore opportunity for select players to have monopolistic share in a market
  • On the other hand apps like Facebook, LinkedIn have very strong network effect - because the barrier to exit for the user is really high!
  • A user has invested time and effort in building a social graph on these platforms with connections, history of exchanges and in some cases even maintain them. It is not easy for customers/ users to switch easily and therefore the “barrier to exit” for the user is really high
