He is suiting the likes of me - who as newby consumer doesnt understand, never will understand, doen't even relaly want to understand, and wants only to cut and paste some HTMl from one txt file to another. AS it stands, he met that goal (and thus addressed how most of the population think).

At the same time, i want the spec to have several "extended" graph examples that showcase how to "do a little more", optionaly. Kingley's examp[le was perfect. Addressing the need for the lifecycle management process (over controlled URIs), he was able to show how to use owl:sameAs so reasoning could handle synonyms (and thus address impact of URI change on ACLs).

THe key is to showcase those more advanced features of reasoning that deliver the message that a linked data client can add some value - and can do so without requiring a huge infrastructure shift.
