I agree.

The ultimate benefit of a Giant Global Graph of Linked Data, is that it 
should  preserve "Individuality" as we pursue or attempt to discover  

What I say in my Web accessible data space  is simply  "My Humble

The Web will ultimately helps us discover discourse as it becomes more 
structured (imho).
