lot of random issues that we can talk about:

–

aside is tangential but related content, it does introduce new section
and, if it is a navigation menu I should write:

[aside]
[nav][/nav]
[/aside]

but hey, I don’t need two nested sections. basically specific section tags, can’t have two roles.

- an article can’t be a nav
- but an article can be an aside
- and a nav can be an aside
- the body can be an article (read below)

–

[article] is useless: If the [body] –IS– the article, I’m obligated to introduce one unwanted section

[body][article][/article][body]

and, after years, there is still not a way to clearly distinguish SITE TITLE and DOCUMENT TITLE

It is supposed that all elements semantically contains some related data to them, but is not:

[aside]
[!-- advertising banners here --]
[h1]Site Navigation
[ul][/ul]
[/aside]

are the banners related? I think not.

Other than saving 5-6 characters when typing, what’s the benefit of using vs for developers, and for users?
