You might also really enjoy Snook.ca. The Six Revisions font-face-guide reminded me of this article (http://snook.ca/archives/html_and_css/becoming-a-font-embedding-master http://snook.ca/archives/html_and_css/becoming-a-font-embedd...) that Snook wrote, and which I have declared to be the most complete guide on font embedding whatsoever. It might focus more on 'front-end development' than design per se, but much of what he offers is invaluable.
