You need to fail in order to find the right solution.

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.

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.

Having a company that's successful is a wonderful platform to do new things. You don't have to raise money for it; you can take profits from the company and pump them into new business.

I have a pretty random life. I run a business and go all over the world doing things for that business, things that are fairly orthogonal. But my job is to run my company, not to be the best Instagrammer. I'll let other people be awesome at it.

On the intimate relationships, I'd say you can be someone who wouldn't normally get attention in traditional media and come onto Instagram and build this massive following.

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.
