Methinks: implementers of RDF based solutions where Linked Data 
principles aren't a concern.

No, I am suggesting that those that process text/turtle should continue 
to do so. That profile is a mixed bag of RDF and RDF based Linked Data 
solution providers.

I am suggesting that RDF based Linked Data providers and the RESTafari 
who are both connected by REST, URIs, and concerned about semantics (at 
the protocol and content levels) meet halfway via the proposed media type.

Kinda think it's the other way around though. By that I mean: RDF based 
Linked Data should have always had a media type which is akin to 
actually doing the dishes.

My permarant about RDF != Linked Data is all about this subtle piece of 
confusion that's ensued as a result of not having a specific media type 
for RDF based Linked Data. This consufion always adversely effects the 
escape velocity of RDF based Linked Data re., tools developers and 
end-users.

We are really close to killing off all of these nuance laced 
distractions :-)
