The best products in the world have a point of view. The worst products have none.

I really appreciate crafts. I like cooking. I love food and drink. I love owning that through Instagram. Although that can be challenging at times because it doesn't fit people's stereotypes of a technical founder.

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

Instagram is a media company. I think we're about visual media. I explain ourselves as a disruptive entertainment platform that enables communication through visual media. I don't think it's just photos. There's a reason we don't allow you to upload photos on the Web as albums. It's not about taking all these photos off your DSLR putting them into an album and sharing them with your family. It's not about that. It's about what are you up to right now out in the real world, how can you share that with everyone.

Focusing on one thing and doing it really, really well can get you very far.

You need to fail in order to find the right solution.

Having a company that's successful is a wonderful platform to do new things. You don't have to raise money for it; you can take profits from the company and pump them into new business.
