OK, I found this: http://www.everything2.org/index.pl?node_id=1194494

It seems the distinction is between people who can't hear (well): "deaf"
and the larger group comprising them and people who support them: "D".

I guess it is supposed to be some sort of internal shibboleth so people
will be able to identify themselves internally as eaher fully
hearing-enabled or not.

But it seems of little consequence to anyone else, at least to me).
Interesting trivia, little more.

Best,
