"The ADDRESS element may be used by authors to supply contact information for a document or a major part of a document such as a form. This element often appears at the beginning or end of a document."
<address> is what people should have been using all along - I remember it was common in academic websites in the early-mid 90s, but it fell out of fashion. Similarly <em> for emphasis, the semantic meaning was lost when people switched to <b> and <i> instead.
