<pre wrap="">For those of us that can recall the exuberance of the XHTML movement,
<i>, <b> and friends were all deemed to be insufficiently semantic and
slated to be replaced by <em> and <strong>. Of course, this was a
distinction without a difference and now we just have extra tags that
are more verbose and less literal.

<p> Not strictly speaking—although <i> and <b> are back
in vogue, <i> is now only supposed to be used for italics
which set text apart in some other fashion as opposed to
emphasising it (which should still be done with <em>). The
distinction may appear “without a difference” for graphically
displaying text in visual clients, but they can represent
considerably different tone changes when reading it out (a
relevant consideration if you are writing, say, an aural client
for the visually impaired), hence using these properly is <em>theoretically</em>
more accessible, though I do not know to what extent that is true
in practice since there's bound to be a lot of deployed legacy,
WYSIWYG or generated-from-Markdown-etc HTML which doesn't make
this distinction, which might preclude relying on it.
