There must be tens of thousands of free typefaces online - everything from schoolteacher cursive to graffiti scripts to famous movie fonts can be downloaded for use in personal projects. But, as usual, you get what you pay for, and the majority of these don't have staying power, and only work in specific settings.
Not so, however, with this great collection assembled by Smashing magazine. It's a list of fine free typefaces (outside the free standards, Arial, Verdana, Calibri) that look mighty fine and would fit in a variety of applications.
Smashing mag also has a regularly updated collection of free typefaces found here.
