Ahh, I thought you were talking about the RDF meta-statement method
where you nest / quote to go meta about something:
(bob knows joe)
(mary said (bob knows joe))
(I think (mary said (bob knows Joe)))
And I have no idea what you meant by "escapes".
Containment in a hierarchy is a way of linking meta information to
something, it is just much more restrictive than non-tree and/or
multiple-"inheritance" methods. Additionally, it is missing the ability
for links between things and having a usually very restricted form of
metadata (directory name for instance).
I think of hierarchical categorization as being equivalent to tagging
with a similar tag path:
report -> /company1/project3/week2
The hierarchical categorization is valuable, it just needs better
grounding in a more rich and flexible semantic space.

A lot I think. Things like this, for instance:
