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

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.

I really value passion for the product above experience.

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.

The best feature is less features.

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.

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