I've used article tags on websites. My understanding and practice is to use the article tag for publication content. I always use HTML/HTML5 tags as their intended purposes and not at will.
Recently, I've seen an HTML template that uses the article tag for the non-publication page content such as the content of an About Us page or any other generic page. I asked the why it was used this way and the (vague) explanation was that it had to do with the way the iPad read the tag. Is this true?
