Actually, the internet is dominated by binary. The wire formats are binary, and a huge hunk of all bandwidth is being eaten up by binary formats: video, bittorrent, voice, JPG images, etc. Sure, HTML, CSS and JS are "text", but it's usually optimized, compressed text, and pretty soon we'll be shipping that around in HTTP2. People optimize what matters. Look at the HTML source for this page. It's mostly user content. More efficient packaging for the HTML structure wouldn't make a measurable difference in load time.
