While reading Laura Kalbag's excellent book, Accessibility for Everyone, I was suddenly struck by the clarity with which she expressed an idea that those of us who build websites too often fail to see:
"Universal web accessibility helps us create sites that are usable by the widest, most diverse audience, rather than creating bolt-on solutions that might benefit one group at the expense of another."
