To those who are familiar with the concept of HTML 5 Outlining, something about seeing “Untitled _______” in the outline bugs me, but semantically, adding a HEADING tag isn’t needed (though I could use CSS to hide it visually) ie
<section>
<p>Test</p>
</section>
Results in “UNTITLED Section”, though the code is exactly what’s needed.
It makes no sense to put “Title Here” when it isn’t there. Similarly to what zcorpan says, picture blind users having the page read out to them with a screen reader. That title might get read to them.
If a section doesn’t need a title, it’s probably not a section. Perhaps you’d be better off using a <hr>.
