Obviously, being the CEO, there are a lot of eyes on what you do and what you post and how you post, and I think one of the challenges of Instagram in general is that, as we get bigger, there are just more voices in the room, more eyes on everyone's accounts.

With Instagram, the focus is on the present tense.

Great products sell themselves.

Working at a startup to make a lot of money was never a thing, and that's why I decided to just finish up school. That was way more important for me.

Every startup should address a real and demonstrated need in the world. If you build a solution to a problem lots of people have, it's so easy to sell your product to the world.

A lot of the earliest Instagram celebrities took really beautiful photos. But you're starting to see a change where it's not about beauty; it's about the story that you tell.

Instagram is a media company. I think we're about visual media. I explain ourselves as a disruptive entertainment platform that enables communication through visual media. I don't think it's just photos. There's a reason we don't allow you to upload photos on the Web as albums. It's not about taking all these photos off your DSLR putting them into an album and sharing them with your family. It's not about that. It's about what are you up to right now out in the real world, how can you share that with everyone.
