Google Introduces Open Source Font API and Font Directory
"For a long time, the web has lagged print and even other electronic media in typographic sophistication," Google Font API team members Ralph Levien and David Kuettel said. "To enjoy the visual richness of diverse fonts, webmasters have resorted to workarounds such as baking text into images."
With the Google Font API, "using these fonts on your web page is almost as easy as using the standard set of so-called 'web-safe' fonts."
These new web fonts work with CSS3 and HTML5 styling, including drop shadows, rotation, etc.
