CEO Patzer says it doesn't sell individual data

Last week during the Data is Money panel at SXSW, Aaron Patzer, the CEO of popular personal finance management Web site, ignited a firestorm of controversy by bragging about the high quality of real time data that Mint is able to see -- such as which movie rental services are used most, and the value it would have to hedge funds.

The notion of selling of user data isn't a new idea, but it disturbed financial writer Felix Salmon and has caused numerous individuals to cancel their Mint accounts.
