while i think that controlling the DNS associated to a URL might be a 
good opportunity to define an "authoritative" answer, this is really not 
the "semantic web".
On the sw everyone can say anything about anyone so that mechnism is 
just a small brick.

If you want a system where you can find all that (participating) people 
have said about a given uri, you might want to take a look at the 
RDFGrowth P2P algorithm,
