Re: "no comment"
"This article is about Mr Novogratz saying that Uber's 'cut' is too high - Uber is overcharging for it's matchmaking services. If he's right, a free market will create a competitor which will kill Uber. One who is willing to take a lower 'cut' and thus is able to charge lower fares (which will steal all of Uber's customers) or pay the drivers more (how well would Uber do if their drivers all left Uber to work for a higher paying competitor?)."
Once 'entrepreneurs' smell the money they will all want in. There are/will be hundreds of wannabe Ubers trying to take the market by being looking cheaper, safer or nicer than the incumbent although usually they just advertise heavily and litigate, They throw money at it, lots of money. To defend against this intrusion Uber will need money, lots of money. They have to get what they can now or lose out later.
