I use a Firefox extension called "NoSquint" on my Retina MacBook Pro and set the default page size to 140%, saving me the trouble of hitting cmd-+ a couple of times each time I go to a new website. That seems to result in a roughly balanced number of pages that are too small and pages that are too large. If I always wore my reading glasses, which I usually don't, I would probably set this to 120%. With reading glasses, my vision on this retina display is razor sharp, and I still think the text on most web pages is too small for maximum comfort.
