Use <article> and <aside>
Use <time>
Use <small> for the copyright

This follows the new semantic meaning of <small> in HTML 5

Quoting the spec:
> Small print typically features disclaimers, caveats, legal restrictions,
> or copyrights. Small print is also sometimes used for attribution, or
> for satisfying licensing requirements.
Use <header>, <main>, and <footer>
