Ok, lots to go at here and thanks to everyone’s for their input so far…
I’m not reading <article> as article, although I do think semantically its function is better suited to being called an <item> for the reasons I’ve already set out, and let’s not forget, HTML5 is all about improving semantics 
[QUOTE=itmitică;5143204]The article element represents a self-contained composition in a document, page, application, or site and that is, in principle, independently distributable or reusable, e.g. in syndication.[/QUOTE]
I’ve highlighted what I consider to be the most important from the spec, afterall <section>s and <div>s are also self contained. What separates the <article> is the purpose of potentially being available for distribution… That’s not to say it ever will be.
[QUOTE=itmitică;5143204]When article elements are nested, the inner article elements represent articles that are in principle related to the contents of the outer article. For instance, a blog entry on a site that accepts user-submitted comments could represent the comments as article elements nested within the article element for the blog entry.[/QUOTE]
Yes, I’ve read that nested <article> comments should also be treated as <article>s too, but it goes against the spec’s description of being “independently distributable”. Why would you distribute a individual blog comment? You would syndicate the blog post with or without their related comments. Taken out of context, if it’s a legitimate comment relating to the blog post, it won’t make sense. I would argue comments would be better suited to the <section> tag.
Everything said here lends itself to my argument…
[QUOTE=itmitică;5143204]That’s the good thing about HTML5, you can use whatever you decide it’s best.[/QUOTE]
This is my main argument, it’s too open to one’s own interpretation. if “you’re” the one deciding the appropriate tag, what’s the point in trying to codify a rulebook for how the tags should be used in the first place? You might as well stick to using <div>s for the complexity and confusion it adds.
Then why bother with these new container tags?
Rest assured, you won’t be alone.
That doesn’t really lend itself to unifying a standard for mark up, does it?
