I disagree.

You're missing a (subtle I grant you) contrast. A resource is
_made_of_bits_, an entity body _is_ bits.

I'm afraid I think this is just wrong. Dereferencing that URL
gets me a different entity body every time, but it's far from
clear that it gets me a different resource. From one point of
view it's a different resource (a constantly changing time-
stamped page), but from another it's the same resource with
constantly changing content. The only thing which is abstract 
is what the resource(s) represent ... the time.



ps. apologies for the earlier HTML mail. Not my fault someone
fiddled with our mail-server and persuaded it to slap a
text/html content type on all outgoing mail.
