I saw this a few days ago. I don't really see much out of it except as a bunch of "standard" class names.
I already build my CSS files to reduce code duplication as much as possible by using generic class names. Because I make stylesheets for different medias (screen, print, etc.), this only sounds obvious and natural. Plus, it's how I roll anyway (I always feel very dirty if I have to write layout CSS that only can only be used for one thing on the site.)
Plus, when I create a design, I don't think "hmm... what existing code can I put in X and Y." I pop open Photoshop and make the graphics work.
