We've picked out Proxima Nova as the main font to be used for Jeff's site. It's darn popular these days, but it looks great with Jeff's work. Simple, clean lines, doesn't force too much personality. We use Typekit so that we can use it on the web. We go through the process of adding the scripts and CSS and stuff needed to use that font.
We use the iOS simulator to look at the header we create with Jeff's name so that we can just the font-size in a real mobile environment better.
