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.

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.

We're just taking people and shifting them from taking photos anyway to taking them on Instagram.

I think Instagram at its best is where you feel like you're getting the most authentic version of the person on the other side of the camera.
