You said you weren't looking for statistics, but I might as well post
this anyway, since it may be useufl.  I did a miniature study a couple
of weeks ago on a list of 62 pages containing the longdesc attribute on
<img>, taken from
http://canvex.lazyilluminati.com/survey/2007-07-17/analyse.cgi/pages/tagattr/img/longdesc

I found that of all of them, two were valid, and none were useful -- one
was for an accessibility checker logo, and longdesc appeared nowhere
else on that page; the other was serving up plaintext files which would
have better fit into the alt text.
