The semantic web may even be theoretically possible to extract some
usefulness out of, too, but don't hold your breath.
Small semantic weblets (intrasemanticwebs? :-) might work out, since they
then work like distributed Prolog systems, but nobody's yet found a way to
make it scale to a global system. Problems include the fact that one group of
people might start publishing tuples of the form "fancies(<url of
Alaric>,<url of Anna Paquin>)" while another might be publishing
"wants-to-snog(<....>,<...>)", which are interchangeable. A bit of software
looking for potential celebrity stalkers would need to be able to deal with
these variations; perhaps some kind of relationship synonym directory
maintained by volunteers, or a central registry that encourages people to
find an existing relationship rather than searching for a new one...
But anyway. What will actually pull together all of these assertions to come
to conclusions (and how will it deal with contradictory or untrustworthy
information)? I see something like Google being the only thing that can
actually make semantic inferences with much utility; for everyone else it'll
be limited to their corporate intranets or they will explicitly subscribe to
information services - "sign up to get hold of a huge knowledge base about
cats", rather than the more peer to peer model of publishing we currently
have.
So I'm skeptical!
