To improve initial load speed and also for aesthetics, I changed the site to use only system fonts. This got me rid of 200kb initial load. The site is now using Plain Old Georgia for all serif text and the system sans-serif/monospace for everything else. Sometimes it´s astonishing how good an old and well-established typeface can look.
Mark Boulton has Arpona in his type specimen newsletter. Beautiful, the type as well as the specimen. The designer of the type is Felix Braden.
