The default font size (16px) appeared a bit too large at first, but after experimenting (in the theme editor, «style.css», content font size)… I just went back to the default… very readable…
Very nice work, indeed! Love at first site, switched to it, right away!!

BTW, the theme uses Microsoft‘s Georgia font, which is simply gorgeous, but if you’re using Linux, where it does not come pre-installed by default, you may want to install the package ttf-mscore-fonts, so that you get to see what the designer really intended you to.
