point taken, but one would expect the uptake on the public side to be
continuing while the other goes on - It is unclear to me why intranet
adoption would favor more expressivity, woudl assume it to be about
the same - a lot of the DOD projects I've been involved with are
using relatively low expressivity w/large ABOX as well
  again, I think the clarity of messaging and the development of a
simpler subset are both necessary to better OWL adoption - i don't
claim sufficiency, but if I have to prioritize (and I do, at least
w/respect to my time and that of my employees) then I would prefer to
see us fill the simplicity gap before chasing the expressivity end -
I think OWL DL/Full is expressive enough to hold most people for a
while...
