Before Mint.com, I was a long-time user of 'Microsoft Money' and Intuit's 'Quicken.' Both were powerful tools, loaded with features and functionality around taxes, investment, budgeting - too feature-laden, in fact. They took hours to set up, forever to learn, and an hour a week to maintain.

The original idea before Mint was a life and goal planning system I called Carpe Viva. The idea was that all of life's goals, from buying a house, getting an MBA, or learning Spanish could be quantified in both time and money.

Carefully calculate the potential size of your market to make sure you can grow. Before starting Mint, I knew that there were about 20 million people who had purchased 'Quicken' or 'Microsoft Money' over the years, and 80 million people using online banking in the U.S. alone.

I always knew I wanted to be a technologist, so I went to Duke and got a degree in computer science and electrical engineering. Really, I thought my goal in life was to be an inventor, a problem solver, so I thought I needed a Ph.D. to be good at inventions, but it turns out that you don't.

There's something magical about spending a Sunday night watching real people at a deli, then watching fake people pretending to be real on TV, then engaging in (arguably) false interaction with (arguably) real people on the Internet. Never at any prior point in time has this been possible.

In my first remarks as Chairman of the Federal Communications Commission to the agency's terrific staff, I stressed that one of my top priorities would be to close the digital divide - the gap between those who use cutting-edge communications services and those who do not.

How can I impress strangers with the gem-like flame of my literary passion if it's a digital slate I'm carrying around, trying not to get it all thumbprinty?

Even though most people won't be directly involved with programming, everyone is affected by computers, so an educated person should have a good understanding of how computer hardware, software, and networks operate.
