I’m very excited that Google announced some high quality open source web fonts. The lack of safe web fonts has always been a pain at times, and the CSS3 font-face is still tricky when dealing with copyrights.
Currently it appears that they’re offering 18 fonts for use. While not a ton of fonts, it is a welcome addition.
Using the Google Font API couldn’t be easier! They offer a great getting started page. Hopefully more fonts will be added soon, and site won’t go too overboard incorporating the new fonts either.
