I agree.  I think the usage of RDF for monolithic models
will be eclipsed by the usage of RDF as the natural language
of the semantic web ... which, if it is to flourish, will
need to adapt to the wilderness of reality, rather than
trying in vain to artificially restrain it.  In fact my
implementation (MyMemory) contains so many contexts (spaces)
that I need to design a context browser to allow statements
to show up when they should.

Unless we can think of a way to communicate in which spaces
statements apply, MyMemory will be shit out of luck when it
comes to communicating about its internal contexts
externally.
