So Facebook buys Instagram for $1 billion. Then last week, out of nowhere, Facebook releases the Facebook Camera app--what is clearly the not-so-secret Instagram knockoff they’d had in development for a while now. In other words, Zuckerberg bought the original, and then he started selling knockoffs. A strange move? Maybe, maybe not. It seems to me that Facebook is buying themselves a bit of time, offering consumers better photo sharing on the go while deciding how much or little they should ingest the soul of Instagram (I’m guessing very little). But it is a fascinating case study, either way, like when Batman and the Joker battle one another one day, just to team up to take down the Penguin on another. And there’s a lot each could learn from one another’s apps. Let’s look at them side-by-side.
