I’m an avid TechCrunch (www.techcrunch.com) reader and thanks to them, I found Mint (www.mint.com). Mint’s description of me is 100% Minty and I couldn’t agree with them more. In my opinion, they have the absolute best way to manage your finances and budgets online.
Think Quicken, MYOB, Microsoft Money or whatever software you might currently use to manage your finances, except that mint puts it all online.
The interface is very simple to use and one of the features I love the most is the ability to send yourself alerts when certain budgets have been exceeded or when large transactions have been recorded. You can have them emailed to you or sent to your phone via an SMS – very cool!
So far I’ve linked up my bank accounts, my credit cards, some of my credit line accounts, my investment account and my PayPal account.

Currently they support some 60,000 account types with more being added daily. They also take your requests if an institution you need isn’t there.
Overall, this is one of the best internet applications I have ever seen (FuseMail being the best of course!).
