Detailed response to Ruben's blog

IMHO, Insightful article on Solid architecture from TimBL.  I found myself
agreeing.

Worth a read.  In particular, I liked this observation:

"The Pod, in RDF terms, is a quadstore, not a triple store. A triples store
is not powerful enough. The 4th part of the quad, the ID of the graph, we
call a 'Document' to make it match with the way people talk. They might be
called Named Graphs or Linked Data Resources but "Documents" is simpler.
The fact that the ;inked data in a pod is basically a set of distinct
graphs is really important."
