Hmmm... I'm not encouraged at all by the tone of this response.

Seems to me that any term which would cause confusion, particularly
in a document intended to reduce confusion, is not "a good thing".

I'm sorry, but I don't find these arguments convincing.

Just because there might be an information infrastructure
which may provide information *about* certain resources
in the form of representations does not make those resources
"information producing".

The definition of the term in AWWW and your description
above feels strained, perhaps from focusing on this stuff too
closely for too long.

I expect the "average Joe" coming cold to AWWW and to the
Web and Semantic Web will end up being confused by the
term.

Right. So again, we're really talking about the "management state"
of representations accessible via that URI, not the denoted resource
itself.

(this is Pat's C vs D issue, of course, such that, for all "information
resources" one could take a C perspective or a D perspective, but
for non-information resources, one could only take a D perspective, 
yet in the context of web-accessible resources, the C vs D confusion
remains; this term does not actually resolve that confusion)

I would hope that you would not presume that just because you've
not heard it before, that it has no merit...
