In section 2 (Strong Containment), the markup example is as follow:
<body>
<aside class='sidebar'>...</aside>
<article class='messages'>
<section class='message'>
Lol, check out this dog: images.example.com/jsK3jkl
</section>
<section class='message'>
I had a ham sandwich today. #goodtimes
</section>
<section class='message'>
I have political opinions that you need to hear!
</section>
…
</article>
</body>
I do not think this is a proper use of <section> (as sections "should" have headings). Looking at the repetition of the class message I'd suggest using a ul inside article with li replacing section; but other constructs could work as well—it is just that I don't think section is the right element here.
