That makes sense. Thus, why can't you accept the same thinking if we 
look at RDF unique selling points as part of such a journey too?

What's wrong with folks arriving at points in the continuum where RDF's 
virtues kick-in without actually being aware of RDF?

BTW -- I still don't know if you accept the world view outlined in my 
venn diagram [1]. I don't want to misquote you, so at the very least, 
could you confirm if you agree with the venn diagram or not.


1. http://bit.ly/16EVFVG -- how Structured Data (Linked Data), Predicate 
Logic (RDF), and Identifiers (URIs) are related.
