Several questions come to mind.

First, can we come up with an objective rating system, vs a subjective
one, in the area of readability ?

An objective system is one that can be used reliabily by different
persons and still give the same answer: e.g. I look at a page, I
looked at the definition of reading level 0 to 4, and I say, this one
is a 3, and so would anyone with the understanding of the definitions.

In the field of metadata for protection of children (i.e. level of
sex, nudity, violence, etc rating), the example would go like:

a subjective rating system:
  0 level of violence ok for toddler
  1 level of violence ok for pre-teen
  2 level of violence ok for teen
  4 level of violence ok for adult

an objective rating system:
  0 No aggressive violence; No natural or accidental violence
  1 Creatures injured or killed; damage to realistic objects
  2 Humans or creatures injured or killed.  
  3 Killing with blood and gore 
  4 Wanton and gratuitous violence

Whereas I wouldn't be able to come up with the same answer as my
neighbour with the first system (what I find OK for my kids is my
business), I would probably arrive at the same conclusion with the
second (either I see gore - as defined out-of-band, either I don't).

Anyway, that's the first issue, and the effort required to come up
with a standard rating system in a given field is proportional to the
difficulty of attaining objectiveness in the ratings. Conversely,
without an objective rating system, we won't go very far there.

The second point is deployment: say we have an objective rating
system, how to we go about having people using it on their pages ?
That means a syntax to encode it (PICS is possible, RDF too),
promotion, tools to produce it, tools to filter on it, etc.

I don't want to paint a dark picture here, but I've been on this path
before with deployment of PICS and it's all but an easy path.
