I re-read Tim Berners-Lee's article [1] and the referenced article by Jakob
Nielsen [2].

What I understand is that there are two opposing forces:

- the need to have stable URIs (as in aliens from the 30th century will be
  able to follow links and bookmarks we save today)

- usable URIs (as in people can remember, type and manipulate them

The recommendation for stability is: encode the point in time when you create
the URI and leave out as much information as possible.

The recommendation for usability is: encode site structure and make them

Thise sounds like a really hard problem that a flat structure like you propose
might be able to handle better, but still is a bit off. If you look at the
actual URLs that I'm referencing, I can't predict what I'll get at usite.com
and the Provider/Style/URI structure of the W3 actually is something they
don't even recommend.
