It's not just for text-to-speech, it's for other "blind agents" (i.e.,
programs) too. For example search engines, which in the HTML world most of
which give higher ranking to ...
<h1>Some Title</h1>
than to ...
<p style="font: bold 36pt times, serif">Some Title</p>
(the latter of which I unfortunately see quite a bit in the wild).

True. Markup is as much -- if not more -- an art than it is a science.
