May be, that's a clear sign that the technical terms don't fit well.
In the non-technical world you can't just define some terms
and expect that people take time to understand them.
For this reason, the terms have to be self describing.
If if they are not, you need different terminology.

I am asking for "permission" or "acceptance" or at least feedback
regarding also to do that. ;-)
BTW, which one is it?

What is so confusing about trust for different thing?
One thing is:
- Do I trust a person (that he/she signs carefully)?
Another thing is:
- Do I trust the computed validity of a key?
Or in short: Do I trust a key?
And s the computed validity is derived from a trust model,
it is in effect the answer to the question of
whether I can trust a key.
And even PGP use the term "trust the key".
May be the whole confusion is raised because we constantly
you try to use all these technical details when they should
For anybody sending encrypted emails the whole point is
only one question:
- Can I trust this key I got so that it is safe to use it?
And I can easily explain that using the term "trust" for both:
To trust this key, you have to trust the owner that signed it
(or trust indirectly marginal trusted owners).
That's so simple to explain and I doubt that this is hard to
understand (although still hard to remember).
And the whole model behind is so hard to explain.
Explaining that a key is "valid" if it is "not only valid
(expired/revoked/disabled), but also trusted according to the web of
trust" is a nightmare.
Don't get me wrong.
It is important to have this fine grained model behind the scenes.
But it is also important to wrap it by something really easy.

As I said, I need some self-intuitive wording for
what technically is "valid".
