When people say that college isn't worthwhile and paying all this money isn't worthwhile, I really disagree. I think those experiences and those classes that may not necessarily seem applicable in the moment end up coming back to you time and time again.

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

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.

Our goal is to not just be a photo-sharing app, but to be the way you share your life when you're on the go.

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.

In the past, people have looked at photos as a record of memory. The focus has been on the past tense. With Instagram, the focus is on the present tense.

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.
