I actually think some of my best moments in life have been while I was with people from Instagram - whether it's super late nights getting a release out or being able to travel to places I'd never visited and meeting some of the most interesting people I've ever met.

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.

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.

Above all else, products spread when they're useful and they're usable

Everyone gets lucky for some amount in their life. And the question is, are you alert enough to know you're being lucky or you're becoming lucky?

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

I grew up as a photo nut. Every Christmas I would get a new camera. It's a huge part of my life.
