I don't think you understand what network effect is. A network effect is where the network raises the costs of switching to another network significantly that they are locked in. ex. FB and your friends.

There is nothing that suggest Uber has a network effect that locks in a user to use Uber. You are talking about a quality effect from the assumption that more assets will lead to a lock in effect but it's hopeful at best. There are no barriers to entry to erode future Uber profits if they make money and no perceived cost of using new entrants services or existing ones.

Well, I think you don't understand what a network effect is. From Wikipedia, "A network effect is the effect that one user of a good or service has on the value of that product to other people."

It's as simple as this: the more users Uber has, the more drivers it will have. The more drivers Uber has, the better the service and the lower the prices. Therefore, a greater number of users leads to greater value of the product (service) to other people.

"You are talking about a quality effect from the assumption that more assets will lead to a lock in effect but it's hopeful at best." I think you're totally missing here. Why is everyone talking about Uber and not Lyft or some other company? Why would anyone switch from Uber to another app if he/she is happy with Uber? Why don't you or anyone else write an app and go create a network of drivers? Because no one will switch, that's why. And that's the effect of the network.

Facebook didn't have any more assets than Google+, except for the users. How is this any different from the "quality effect" you are talking about?
