You know what I like about books? They're printed using black ink on white pages. I have to believe that other readers prefer this high contrast approach or we'd see more variations after centuries of printing. Do your visitors a favor and use black text for your main content. The light grey on white surrounded by light grey makes me reach for my glasses, then I realize I'm already wearing them.

Other than that, I really like the site and added it to my bookmarks. I would like to see the number of reviews without having to hover over the cover, though. It helps put the score in perspective.

Books are constrained as much by medium as readability. If you want the book printed cheaply, you're relegated to black text on an off-white background. Also, there's a big difference between text on a back-lit display and text on a page.

I think dark gray text is a good choice for text on computers.

What the dark grey (it isn't really super dark) text actually achieves here is to allow your attention to be drawn to the pictures of book covers.

This, of course, makes the site prettier, because book covers are colorful.

Personally though, I'd rather just have a list of [book name - author(s)]
