I was thinking the same thing lately when I was creating some descriptions 
for my very visual slides: most users would benefit from these descriptions 
not only users who have visual disabilities. However, right now many user 
agents don't offer the longdesc info easily to users or even information 
that it is available. So I selected to use both D-link and longdesc.

Rather than using D-link instead of longdesc I think the user agents should 
be corrected (did not check UAAG but it should be mentioned there).  We 
don't have to think that only screenreaders use longdesc features. I'm sure 
there exists an acceptable way to provide longdesc info to everybody 
interested in all user agents so that those who wish can benefit from it.
