Mint - Yummay!
Fantastic Business Model. I have been using Mint for the past two years now and it has made me realize how much money I burn each month.
Living up to its self-proclamation as the "best free way to manage your money," the browser-based application is designed to serve as your own personal financial adviser. If you want the ultimate, interactive, complete bank statement, Mint is exactly what you're looking for. It can grab all your spending data from everywhere, add it all up, and let you know exactly how much money you've spent -- and on what -- from any Web browser.
