The only real difference is instead of shuttering they pivot. The name sticks around but they still delete all your old stuff[1], so the effect is the same.

Facebook doesn't want to "do one thing". The problem is, Facebook keeps failing at doing other things, so you never hear about them or remember them.

Hey, what do you think people remember best: The facebook phone or the iTunes social network?

But social networking is the core of what Facebook does, and that includes the failed phone. G+ is pretty much irrelevant to Google's core businesses, which are search and advertising.

Clearly, Google should just focus on their cars.
