This is an awesome explanation of why we care about how people choose to
use http: identifiers.  The semantic web is about interoperable
metadata.  If the metadata can't flow, aggregate, and interoperate, it's
*not* going to be a semantic web.  Interoperability means that if I
aggregate 500 different assertions from different sources, all about
http://www.microsoft.com, I know that they all are talking about the
same "thing".  If I can't even guarantee that much, then all of this
semantic web talk is a waste of time.  I hope people can see from Sean's
example why this is such a fundamental thing to get out of the way.
