To make things more confusing (for me, at least), section has an optional attribute for cite in the event it is taken from an external source. If it isn't "a self-contained composition in a document, page, application, or site and that is intended to be independently distributable or reusable," then why do we need the cite attribute? Wouldn't we then use the article tag?
Or is it simply that the cite attribute is there if we DO take something from another website that wasn't intended to be independently distributed? In such an event, though, I would think that the blockquote tag is then the better option.
Semantics: gotta love it.
I just found this article: http://boblet.tumblr.com/post/130610...ml5-structure1
I'm not sure I agree with all of it, such as when he says:
Also avoid nesting an <article> inside another <article>—use <section> for indicating logical parts of an <article> instead.
In one of the examples article element examples
it nests an article (comments of an article) inside of the main article.
