The number of people who have either gotten married or had kids or started dating or just made great friends over Instagram is countless. I think we're the only platform that continues to be successful in bringing people together in real life for these real relationships.

People interact with their phones very differently than they do with their PCs and I think that when you design from the ground up with mobile in mind, you create a very different product than going the other way.

What people tell you and how they act is very, very different sometimes.

Every photo you take communicates something about a moment in time - a brief slice of time of where you were, who you were with, and what you were doing.

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.

The major reason why Instagram works is that you can follow anyone out there and start following their photos immediately.

People have presences, both online and in real life. You can choose to show everything, meaning all sides of you, or you can choose to be selective.
