Dorsey: "I'm less interested in how people are following each other and more interested in how they are following topics and tweets themselves. People are following more key words and concepts and more ideas and acting on those rather than individuals or organizations."

Dorsey: "My goal is to simplify complexity. I just want to build stuff that really simplifies our base human interaction."

Dorsey: "I love cities, and I love city governments in particular. But in politics it would have taken me 8 years from implementing a policy before I would get to see the feedback. With programming I could model the same policies and see the impact immediately. Technology is a far more efficient way to test."

Dorsey: "There's an entire universe in every single tweet, and it all really depends on the content as far as how it's going to spread."

Dorsey: "Twitter has been my life's work in many senses. It started with a fascination with cities and how they work, and what's going on in them right now."

Dorsey: "I think Twitter is the future of communications and Square will be the payment network."

Dorsey: "I am someone who tweets about what I have for breakfast, what I have for lunch, what I have for dinner, and for 99.99999 percent of the world, it's useless. It's meaningless. But for my mother, she loves it."

Dorsey: "I was fascinated with jeans, because you can impress your life upon the jeans you wear. The way you sit imprints on the jeans."

Dorsey: "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."

Dorsey: "I fell in love with flora of all types, especially ferns. Loved the sparse structure and repetition of shape - almost fractal."

Dorsey: "A number of people in the United States, almost everyone, is using plastic cards to pay for things, but it's extremely difficult to accept these cards. So let's make it's easy and take more and more of the friction out as we can."

Dorsey: "I think Twitter is best when it sparks conversations elsewhere."

Dorsey: "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."
