I don't think it's that strong a network. Drivers are businessmen - they aren't going to shun another app just because it's too much trouble to sign up. So there's big no chicken / egg problem - any competing network with half a chance of taking on Uber will get plenty of drivers. It's kind of like eBay stores, not the "sell and buy junk from strangers" eBay. And since there's only one product, the customers won't flock to Uber because they want variety. I'd rate it lower than eBay and far lower than Facebook in terms of the strength of the network.
