Take away the display of font names until you mouseover an image, and you have a fun game for font nerds! Could probably write that in a few lines of JS and apply with GreaseMonkey.
Ask 100 Programmers what their favourite font is and you get 100 answers :)
I'm a big fan of Proggy (the clean / slashed zero / bold puncutation one) combined with a light color on a dark background I can stuff as much code on my monitor as possible without straining my eyes. That way I believe to better oversee the structure of the code and need to scroll less, but each to his own.
