HTML5 <article> Tag

The <article> tag specifies independent, self-contained content.

An article should make sense on its own and it should be possible to distribute it independently from the rest of the site.

Examples of possible articles:

forum post
newspaper article
blog entry
user comment

Example:

<article>
This is a test article.
</article>

All the latest browsers support this property.
