AOL's latest project is WalletPop, a personal finance counterpart to their popular site money.aol.com. The latter is oriented towards investing and business/finance news, while the former is simply here to help you manage your money better.
The site is quite 1.0-ish in both appearance and functionality, and there's really nothing wrong with that. Without beating around the bush, WalletPop offers a comprehensive list of various calculators - credit & debt, mortgage, auto loan and the like - plus a bunch of advice aimed to help you save more and spend less. Dig a little deeper, and you'll find some nifty services, such as deal finders and tax forms.
With this latest project, AOL has nicely rounded up its inventory of finance-related sites; although you can get lost in all that info, it's still organized well enough that it can be a main and perhaps only stop for all your investment&finance needs.
