No, the real distinction is whether or not you can give a URI to
something that doesn't exist yet.  You cannot do so if what you are
naming is a document, whereas you can for a concept that is only bound
to a representation at the time of a request.

Authors live in a different timeframe from the people that traverse
their web.  The effect of the technology and the design of HTTP is
to take an author's wishful thinking and attempt to realize it at
some future date for some future user.  The Web is a network of
wishful thinking that becomes an information space in the timeframe
of any given user, with occasional gaps when the wish wasn't enough
or when the concept has yet to be realized.

Use the technology and think about what it implies.  This is not just
my opinion, it is my experience, and it isn't going to change.
