If you haven't already seen Jessica Hirsh's portfolio of typography, it could change your life. Jessica is the woman behind the daily drop cap and her other work is equally inspirational. I just love it all!
So I've been following Fontfabric for awhile. And I'm always waiting, watching and anticipating their next font, and quite often it's a free one. Even the fonts that aren't free are decently priced. The free ones are always a little funky, not 'exactly' legible, but definitely fun. It's worth checking out and their designs for promoting the fonts are nice eye candy as well :)
