<address>
How to reach whoever signs the text — and nothing else.
It is not for postal addresses in general. The content has to be a way of contacting the author of the nearest <article> or, failing that, of the whole document. An address quoted inside a news story is ordinary text.
Browsers italicise it by default, which led plenty of people to adopt it as decoration. The semantics are what matter: they are how a screen reader knows to announce "contact information" on entering the block.
