Because you already get it. What I mean by that comment is the fact that 
you already understand what RDF actually is. There are many others that 
have a gut reaction to RDF (for a myriad of reasons) and the net effect 
is more about the letters R-D-F and less to do with what it stands for, 
however imperfect its narratives have been in the past.    (02)

Bearing in mind the problem some have (instinctively) with the letters 
R-D-F I attempt to plot an alternative route to the same destination by 
showing that de-referencable URIs combined with entity-attribute-value 
model constrained structured data representation is what Linked Data is 
about.    (03)

There are more folks that understand what the entity-attribute-value 
model is than there will ever be those that grok RDF (again: because for 
some the errors of the past are simply fatal). Thus, bearing in mind 
this reality, why not just crack on with the main destination (Linked 
Data) however we get there. At the end of the day, without Linked Data 
there's zilch re. Web scale structured data that's based on Web 
Architecture DNA etc..    (04)

Note point #3 reads:
Provide useful information about the thing when its URI is dereferenced, 
using standard formats such as RDF/XML.    (06)

Of course in reality, we have to decompose further and it should really 
mean:    (07)

Useful information == structured data (entity-attribute-value or RDF  
model constrained)
Formats: various, which means a variety of syntaxes and serialization 
formats for structured data.    (08)

Somehow, the above evolved into an odyssey or boundless proportions    (09)
