Yes, but symbol manipulation is not grounding.  Just manipulating symbols
without grounding them to reality is but an academic game.  If the semantic
web (or cloud) is to be useful to us for anything, then it must be grounded
in what people want to do.  I believe that was the thrust of Grahm's
question, but perhaps not.

The question is what is the space from which we "escape" into logic and to
which we return... methinks that space is the dialogues that users have with
their computers and with each other ... those active processess including
the intentions and contexts of which they consist must be our grounding.
