Hi Gregory,

I have known about the @longdesc for years, but have never actually  
used it... but a description like that really shows how useful it can  
be.

It could be argued that such a description should exist on the page  
itself... but I am sure there are cases where this is not possible or  
relevant... in which case, I hope the contents of the @longdesc  
become available for all users, though the standard setup of all  
browsers (not just though extensions).

Perhaps if browsers made users aware of the @longdesc, we might see  
more of its use... perhaps like how Firefox 3 is making users aware  
of micro-formats, by visually changing the mouse cursor.
