The site's text is medium blue on a gray background with a font-weight of 300. I'm all for a bit of visual variety and personal expressiveness but this is pushing the boundaries of accessible legibility on some systems and screens.

(Yes, I realize there are various browser accessibility tools, reader modes and even custom CSS overrides, but I'd prefer not being forced to force those things on for all sites - because it means that "bit of visual variety and personal expressiveness" no longer exists for increasing numbers of visitors.)
