> A little less contrast
WHY. WHY DO PEOPLE DO THIS. To give this person credit they have at least chosen some sensible values, rather than gone with something that was just about enough on an expensive graphic designer high-contrast monitor and then not tested it on anything else. Leaving the rest of us squinting to try and read text or manually overriding CSS.
Despite not being a complete idiot, they have still made the content harder to read. Contrast is good. It makes things easier to read. Why would you want less? Yes I know the art theory stuff about never using black because it doesn't appear naturally. You know what else doesn't appear naturally? TEXT. Black on white is a perfectly acceptable default, please don't change it for your body text without a really good reason.
