I'm writing about the <article> element now. To preempt myself, I just want to say: it's completely useless. I never use it. Why? Because it's designed to represent an independent piece of content BUT since the document outline algorithm has never been implemented and the element (inevitably) appears as part of a larger web page, it should be introduced with an <h2> heading. BUT it makes no sense to head an "independent, distributable" piece of content with a subsection heading. Trash 0/5.
