You can be a couple in London who happen to take pictures of their breakfasts every day - it's called @symmetrybreakfast - and you can gain hundreds of thousands of followers overnight because people are genuinely interested in your unique angle on the world.

The number of people who have either gotten married or had kids or started dating or just made great friends over Instagram is countless. I think we're the only platform that continues to be successful in bringing people together in real life for these real relationships.

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.

You need to find people that are drawn to the idea that you build, and they end up taking it and making it even better.

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?

Instagram was created because there was no single place dedicated to giving your mobile photos a place to live and to be seen.

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