I got confused too.  A SPARQL endpoint is a service endpoint. But a URI 
or (HTTP GET in your opinion) represent a resource. Of course, the 
former can be used to help the later, but I don't think it will ever 
replace the latter.

I agree with David too. I think Jonathan has interpreted the 
"authoritative" too literally. The "authoritative" in the Web means more 
about the "authorship" of the resource.  It has nothing to do with the 
right or wrong of the statements.

Perhaps because my argument is always that the URI problem is a much 
more fundamental problem.  Using SPARQL endpoint to solve URI's 
stability is like an acrobat trying to balance himself on a string. Sure 
a skilled acrobat can do it to a great extent, but no matter how great 
his skill is, he won't eliminate the danger of falling off unless he put 
his footing on a solid ground.
