Looks like this article is over a year old, so some of the technical solutions or opinions may be a bit outdated now.

Well, what helps is a set of black and white rules, whereas too many new HTML5 tags are open to personal interpretation. When is a section not a ‘section’? When are ‘details’ not actually details? And so on. Maybe I need to get out more, but these are the things I find myself dwelling on more now than I ever did with HTML4. It’s progress of sorts, but I can’t help feeling the rules could be more rigid.
