'Instagram' can engage generations of people that may not be on Facebook yet. I think that's true with 'WhatsApp,' and I think that will be true with things like Oculus.

A platform is the base from which something big happens. In our case, we're an entertainment platform in the sense that there are people signing up like MTV, Burberry, folks like Taylor Swift and Justin Bieber. And why? Because it's their channel to control their entertainment to their fans.
I don't foresee a future where people don't have some sort of phone that's like a computer. I don't foresee a future where those phones don't have cameras in them.

There are fun parts of running a startup and not so fun parts, and Facebook handles the not so fun parts, like infrastructure, spam, sales. The real questions are, how big can 'Instagram' get?
