According to a report from Bloomberg today, Mint.com's CEO Aaron Patzer is considering selling anonymized data about the service's users. Mint, the online personal finance aggregator, obviously sits on a lot of very interesting data, some of which the company has shared on its blog now and then. Given that this was just a short interview, the details about this plan are more than vague, and it would be interesting to know what kind of data Mint might be planning to sell. What is clear, though, is that Mint will have to be very careful if it doesn't want to scare away its customers.

Back in September, Visa announced that their Visa Mobile Application would become the first financial application for Google Android-powered handsets. The application, launched only days ago, lets users receive notifications on their mobile phone about their account activity, receive offers from merchants, and use GPS to map out where those mobile offers can be redeemed or to find ATMs that accept Visa.

Fidelity, one of the world's largest financial service institutions, has just launched the first iGoogle secure banking gadget for use by their tens of millions of customers. With the new Fidelity Secure Gadget, customers no longer have to visit Fidelity.com or NetBenefits.com in order to check their account balances - they can now do so right from their own iGoogle homepage.

Given the U.S. economic crisis, people are looking for new and better ways to get a handle on their personal finances. We recently profiled 10 money management web applications that promise to do everything from analyzing your spending behavior to saving you money by negotiating lower rates on credit cards.

The proliferation of these types of apps would have you believe there's a big demand for web-based financial tools. But is there really? We would hope so, considering how their advanced technology can provide detailed analysis about your money (or lack thereof). However, we secretly wondered if the only people logging in to sites like Mint.com and the like are the young kids of Gen Y. Do adults with mortgages, credit card debt, and 401Ks even know how to use these tools?

There was a time when managing finances from your computer meant you had to use desktop software. Today, that's no longer the case. There are now a number of applications that let you do your banking in the cloud, a trend we've dubbed "banking 2.0."

These sites aren't just simplified versions of our former desktop apps, either. Instead, they offer a number of features that take advantage of their "always on" status. Forget downloading updates and typing in your transactions line-by-line, these new banking 2.0 sites can offer you better insight into your financial situation with no additional effort on your part beyond just logging in.

When Mint.com launched, they were taking a big risk - would people trust a web app to manage their finances online? Web 2.0 apps don't necessarily have a reputation as offering hardened security. However, Mint's efforts to prove they were safe and trustworthy won people over as did their easy-to-use personal finance tools. Today, Mint.com serves nearly 400,000 users, manages over $12 billion in transactions, and has saved $100 million+ for its users. However, one problem the site has struggled with was keeping its users informed as to all the new features of its product. Today, the Mint.com site gets an overhaul to specifically address this issue.

We've been taking a look recently into the troubles at online auction and ecommerce giant eBay. Ten days ago we took a look at reasons why many sellers are leaving eBay, and yesterday we covered an Australian ruling that barred the company from forcing sellers to use PayPal as their only online transaction method. Despite the problems the company is facing, their total listing numbers appear to be on the rise. But could they be artificially inflating that number?
