Well, what do you mean by that?

The user agent that WCAG WG has historically custom-crafted its guidelines
to cater to, Jaws on IE for Windows, can read a longdesc. Window-Eyes
supports it. You can read longdescs in Mozilla. There are other
implementations, for all I know. (iCab, even, not that it really counts.)

It's in the spec. Some user agents support it, and the rest of them are 
gonna have to eventually.

The D-link option was always a kludge and simply is not justifiable. It is
extra-specification: To endorse it is to concede that the HTML spec isn't
good enough. It says the spec is so bad, in fact, that we have to
recommend nonstandard workarounds. Well, why?

I think not.

How's that gonna work on photoblog pages with valid code and correct 
alt-text usage?

(using null alt text when adjacent text does the job)

Where are you gonna put 20 letter Ds?

(Hi, Chris!)

Let's stick to the spec.
