This blog, by the way, uses Georgia. I also love Gill Sans (especially Roman), and would love Johnston Sans (designed for the London Underground). Helvetica, of course, is the most progressive and lovely font outside these two (now a major motion picture). Do you have a favourite typeface?
(By the way, for the purists, I know that the title of this post is inaccurate. Fonts and typefaces aren't the same. But I was desperate for a good pun).
