This is great news. However, all this discussion of "semantic this-or-that makes my site look like shit" or "semantic tags are just for template clarity" and "well at least web crawlers and Readability can make use of it" is really annoying.

If you think <main> exists to make SEO easier for you, I'm willing to bet that around 7 million blind people in the US alone won't bother trying to use your site. Why? Because their screen reading software won't be able to make it through your mess of markup and get to the part that matters, for one.

It's hard enough getting people to care about accessibility at all, but trying to drive ARIA adoption must be a complete nightmare. <main> is taking one of the most obvious, simple, and useful pieces from ARIA, which just happens to fit in quite sensibly with existing "semantic" tags, and allowing you to remove an important accessibility hurdle without even knowing about ARIA!

I, for one, am extremely glad that I can now make my sites a bit more accessible with almost no extra effort.
