"As soon as the funding closed Facebook was suddenly facing a viable threat in mobile vs. just another resource-starved startup hanging onto dear life." You are stating that like it's a fait accompli that the threat is real and a done deal as opposed to a mountain that they have to continue to climb and achieve with all sorts of things that could cause the dream (after $500m funding) to not even happen. Perhaps it's the same bias on the part of Facebook that caused them to make this acquisition and overreact (possibly - and of course we'll never know the answer) to Instagram's funding. And what about the fact that they waited until they were funded as opposed to having a system in place to identify the threat from "just another resource-starved startup hanging onto dear life" and getting involved before that?
