Build what you want to see in the world.

Anything you're interested in the world whether it be Charlie rose or JetBlue or a public figure or your local coffee shop, they're on Twitter and broadcasting what is interesting to them.

What I love about New York is just the electricity I feel right away.

Twitter was around communication and visualizing what was happening in the world in real-time. Square was allowing everyone to accept the form of payment people have in their pocket today, which is a credit card.

It's empowering to be asked to look at what's possible, not told how to do it.

I said a long time ago that Foursquare can make cities better. You have these augmented realities like Foursquare and Twitter and Facebook that provide these virtual nodes and instant feedback from anywhere, adding annotation around a physical places.

Pick a movement, pick a revolution and join it.
