Today Google announced they'd help advance web typography by hosting open-sourced fonts on their CDN, and by giving the code to easily embed fonts on websites on a new website, the Google Font Directory.
It was amazingly simple: just copy the <link> code and paste it in your template's header, then set any element on your page to use the Google-provided font(s). I started using OFL Sorts Mill Goudy TT, and I like the look (except for the lower-case y, which seems to be cut off).
(The code simply adds an @font-face declaration via a Google-hosted CSS file... I wonder if it's legit to self-host the CSS and font file; I haven't read through the terms and conditions yet).
I'm thinking of using this library for a few other projects on which I'm working. Much easier than Typekit, and it doesn't require any javascript or flash overhead, like alternatives such as Cufon and sIFR do.
