article is related to section, but is distinctly different. Whereas section is for grouping distinct sections of content or functionality, article is for containing related individual standalone pieces of content, such as individual blog posts, videos, images or news items. Think of it this way - if you have a number of items of content, each of which would be suitable for reading on their own, and would make sense to syndicate as separate items in an RSS feed, then article is suitable for marking them up.
In our example, section id="main" contains blog entries. Each blog entry would be suitable for syndicating as an item in an RSS feed, and would make sense when read on its own, out of context, therefore article is perfect for them:
section id="main"
article
!-- first blog post --
article
article
!-- second blog post --
article
article
-- third blog post --
/article
section
Simple huh? Be aware though that you can also nest sections inside articles, where it makes sense to do so. For example, if each one of these blog posts has a consistent structure of distinct sections, then you could put sections inside your articles as well. It could look something like this:
