I created an account with Mint.com a few years ago when it first became available. At the time I didn't like the UI (among a fre other items) and eventually using it. The other week I decided to log in again and see what changes have occurred. (I knew they had been bought by Intuit since I last used them.)
Improvements look good. The credit card tracking is much better and purchases are placed in appropriate categories. Home prices are now tracked through Zillow. One improvement I could recommend is if car values could be tracked with KBB or something similar. This would make it much easier than manually having to adjust for depreciation annually.
I plan on using Mint for a few months and see what kind of insight I can glean. It's another good tool for the PF toolbelt. Perhaps I will find it more useful this second go-around.
Do you Mint? Or with a similar online service?
