The whole point of this is to have a handel to extend the current 
technology such that the discovery of the entire graph or at least a 
large portion of that graph *will* be possible.

Naming that which you want to find is sometimes the first step in 
finding it.  In this case the name of the graph is necessary so that 
many agents can *cooperate* to discover it.   In fact just quoting the 
URI of the context on your blog should help Google do most of the work 
for you.
