I am sorry to say
but logics has only one way.
I too don't usually come
to Marc defences as one.
This time I think say one might
that his statement was (almost)right.
Ok, I am not a poet, and of course his proposed negative test (as in
non-spam test) will probably add nothing to the usual criteria, but
the real problem with his test is not with its validity, it is its
non-cacheability (ouch!).
