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.

In my fourth grade classroom, I even instituted a government structure, because I was really interested in people having positions and there being law.

We just want to build a company that focuses on the love of Instagram.

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.

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.

I always look toward teens on Instagram to really understand what's going on. For some reason, when you're a teen, you just understand the world better than anyone else.
