But if you are constrained by your team (ie, you can't work on everything at once, which Facebook says is their biggest constraint) and you have plenty of easy money from investors, why would you try and profit now and risk another service taking your audience when you could possibly build something that can profit for years to come?
Constrained by your team? I can see you making that case for Instagram with only 12 people, but according to Yahoo Finance, FB has about 3500 people. Not one of them is thinking about how to increase revenues? And they don't have enough engineers to try out some of the ideas?
True.
