I'm afraid I have to agree with a lot of this.  The original philosophy 
behind HTML and any suggestion that authors have a responsibility for 
correctness, are lost causes as far as the people responsible for the 
main stream competitors to IE.

The name of the consortium that created HTML5, WHATWG (spelling?) is an 
abbreviation based on the phrase "web applications", so, yes, they are 
not primarily creating a document language, however commercial use of 
HTML on the public web  has tended this way for a long time, with people 
essentially writing custom browsers in ECMAScript, because they consider 
using standard controls doesn't differentiate them enough.

CSS is going in similar directions, with it becoming more and more 
difficult to argue against new features on the grounds that they 
encourage bad practice, and any suggestion that CSS only hints at 
styling being considered unreasonable.  However, CSS, at least, never 
was about structure.

I wrote a much longer piece on this about a year ago, so won't repeat 
myself here.

Only on WAI list.  I don't like cross-posting, and posting to the HTML5 
lists will be counterproductive.
