I guess in two ways. One is structural - you could end up laying out 
@class tags in ways that's it hard to pull back structured info (be 
it 3-tuples or somethin). The other is idiom - that is, it's not 
idiomatic to use URLs in @class attributes (I don't recall if CSS 
syntax would support such URLs).

On the other hand, doing something as simple as hacking blogging 
catgeories (many people have maybe half a dozen or so) onto URLs can 
give you quite useful metadata. For example, I tend to use WikiWord 
syntax on the basis that someday I'll get of my arse and merge that 
namespace with my Wiki. So you can prime things in low effort ways.

In practical terms @class is still very useful; I have a colleague 
in Propylon, Clyde Hatter, who leverages @class attributes in markup 
to great effect.

I think so; it can be good enough or useful enough given the burden 
that's been taken off the user.

:) Fwiw, I don't buy into the more GOFAI visions. I don't see that 
we'd neccessarily reach a semantic inflection point without a 
statistical/signal processing layer in the architecture doing the 
bulk of the work.
