Just curious? What are the fonts used?
Typography here is still pretty messy (one of these days when we do a design overhaul I'll put serious work into making it up to my standards), and it depends on user settings (e.g. you can change your post fonts from a serif font to a sans-serif font) but here are all the fonts in our CSS file:
"Trebuchet MS",Verdana,Arial,Helvetica,sans-serif, Courier, monospace, Georgia, Times, serif, "Lucida Grande"
Especially in the logo? Or the closest equivalent if it was modeled after a hand drawing?
Logo is slightly tweaked Futura Lt except the 2, which is "Poor Richard" with a dot added to it.
