Phill, this is a great answer. I'll claim that it's just not the right question.

The Right Key has nothing to do with safe user experiences. Marginally, we 
could address the sort of question such as "what does the SSL lock *mean*?" but 
even that's pretty ill-defined. It also goes beyond whether trustworthiness 
(whatever it means) is within scope.

I still claim that we should not go near trustworthiness because I'd rather 
come up with one good solution than several vague ones. The PKI debates of 
fifteen years ago bit off more than they could chew, and that's part of why 
we're here. I think we need to do less before we do more.

        Jon
