How to choose the right face for a beautiful body

I can’t put my finger on why, but lately I’ve been skipping a lot of Smashing Magazine articles. That changed with Dan Reynold’s breakdown of body fonts. Very true to Smashing form, Reynolds’ coverage is exhaustive. A few times it becomes too exhaustive (I have doubts on the effectiveness of font ‘apertures’), but this is awesome stuff. I knew a lot of the basics (e.g. go for moderate stroke contrast, higher x-heights), but there’s a lot of info here I haven’t seen anywhere else.
