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.

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.

What's awesome about social media is you curate your own experience. That leads to the rise of niche celebrities, who are actually just as popular as mass celebrities, but because there's no incentive for traditional media to invest in them as celebrities, they find a home where people can follow them on Instagram.

I was never as focused in math, science, computer science, etcetera, as the people who were best at it. I wanted to create amazing screensavers that did beautiful visualizations of music. It's like, "Oh, I have to learn computer science to do that."

I don't think you should ever start a business and move in a direction where you can't see it becoming a business.

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.

I believe photos is one of the underlying things in every social network that becomes successful.
