I don't either, but it seems to bear on open versus closed systems. doesn't
it?  Are there true statements not in the graph or not?  Usually people say
(I think that includes you, right?) that the Web must be or is an open
system, while those interested in definitively proving things would like a
system to be closed.  Perhaps this gives you a way to construct a closed
system if you need one.
