I guess your point is that 'what the random.org RF noise sensor
detects' is like 'the weather in Oaxaca' (or maybe: 'a report on the
weather in Oaxaca'?), but I've never been satisfied with the AWWW
account of that 'resource' either. It seems alternately mystical,
tricky, and vacuous. I was hoping we could do a bit better here.

Regardless of whether you think my examples are, the question of
non-REST resources remains. You might say that there aren't any
non-REST web resources - that REST is nonfalsifiable, a tautology.
Given any kind of server behavior you can always post hoc invent some
resource and resource states that fit it. But if REST isn't
falsifiable then why all the fuss over it?  In Roy's writing and
elsewhere it comes out sounding like a recommendation - and that only
makes sense if it's a choice, i.e. if there's a way to *not* follow
the pattern. If so, given how wild the Web is, there must be cases
where someone used HTTP correctly, but did not follow the REST
