It seems to me that all of your angst centers around the question of  
which URIs can be resolved and result in RDF content (selections from  
your responses that I consider evidence are below). Essentially, you  
are saying don't use <http://....> unless there's some RDF at the  
address in between the <>.

This is indeed an issue, and I have complained about it myself.  
However removing a selection of things from the universe of what can  
be discussed on the Semantic Web doesn't seem like a great solution.  
Instead we need to agree on a practical protocol for figuring out,  
given some URI, how to go about getting the RDF documentation that  
describes the entity that the URI names. I think that's within reach,  
and given you mention you've been browsing the neurocommons.org web  
site, you should be aware of what our thinking is on this matter.  
Basically it boils down to, for starters, a) Giving a rdf:Type to  
resources that are RDF formatted. b) Tightening up the protocol by  
which one is supposed to find RDF so that it is predictable. (No vague  
"see other" stuff. No unconstrained content negotiation. Some work to  
establish a shared ontology in this area).
