that, too, should be made more explicit in the how-to guides. they tend to
range from instructing people to "sign the key and then you're done", to
"upload the signed key to a key-server."

what if i was personally introduced to you as "atom smasher"? what if i
was introduced by someone who we've both personally known for years? what
if i was speaking at a conference, and identified as "atom smasher"?
assuming that you don't have any faith in who i claim to be (which is up
to you: i have to admit, i am suspicious), would you sign a key based only
on verification of an email address? would you sign it as:
* "I have not checked at all (1)"?
* "I have done casual checking (2)"?
* "I will not answer (0)"?
would you use a unique policy-url to describe the conditions under which
the key was signed? what might it say?
i'm not trying to put you under the spotlight or prove you wrong; nor do i
think there are any "wrong" answers. i'm trying to provoke the exchange of
ideas on how to solve this real-world problem... i'd actually like to hear
from anyone who can explain an answer that makes sense to them.

~someone~ has to go first, right?
