It's not just about reproduction, but composition, as well; the referenced site uses far too many words per line, at too small a font, to be reasonable legible (it's actually a perfect object lesson of what NOT to do). Sans serif font faces, on the other hand, manage to be readable at smaller sizes, and even more so on modern anti-aliased displays, where they support a greater number of words per line. Lest it seem that I am biased, serif fonts continue to be the best option for so-called "display" purposes (i.e., short line length such as headlines), as well as for subtractive, engravure-based applications such as stone, metal or wood; in these applications, sans serif fonts fail to provide a reasonable sight line.
