Who is the user? The author or the visitor? It sounds like you are  
talking about the author.

As mentioned previously, separation of concerns is a good thing. "I  
am writing HTML, therefore I am entering content and describing its  
semantics". "I am writing CSS, therefore I am describing how the  
semantics should be represented to the user". It isn't difficult, it  
lets authors think about one thing at a time, and it lets multiple  
people contribute to a document (with a CSS expert working on the  
look while HTML experts work on the content).

If your goal is to put the presentation and semantics into the same  
place, then just go back to HTML 3.2. Otherwise you'll end up trying  
to squeeze content into CSS, and the structure of the language  
doesn't lend itself to that.

I'd say that this would make life more complicated for authors and  
for machines. So both sides would have a net loss.

It sounds like you are advocating a really complex solution that will  
just reduce bandwidth use and typing for a few edge cases. In  
general, having presentation in CSS and semantics in HTML works just  
fine, with little duplication of effort.

Not given the statement you responded to.

I have no idea what this is supposed to mean.

A plus sign is not an answer.

(a) Garbage. If something needs more processing, then it will take  
more time given the same hardware.

(b) What about "realtime" UAs?
