In HTML5 the <cite> element shouldn't be used, when referring to a name/author.

The Release Candidate proposes the <b> ​element, which sounds fair enough. obenland mentioned, that it would also set itself apart from the sorrounding <span>.

Right, I also think <b> is a bit less generic than <span>.

+1 to this change. A brief look at Twenty Thirteen, no changes needed as we don't style that particular element with a cite in any selectors.

Replying to lancewillett:

A side effect will be, that the font will be bold, which can be fixed by adding font-weight: normal to .comment-author .fn.

In 24535:

Twenty Thirteen: ensure b element in comment markup isn't bold. Props ocean90, see #24522.

In 24539:

Replace the cite element with a b element to markup the comment author in comment_html5().

In HTML5 the cite element isn't valid for just an author's name.
"The cite element represents the title of a work .. A person's name is not the title of a work" (​http://www.w3.org/TR/html5/text-level-semantics.html#the-cite-element)

fixed #24522.
