Right, so why is it any better to have a key with:
0x99242560 David Shaw <dshaw at>

than to have
0x99242560 David Shaw
0x99242560 dshaw at
(two UIDs)

You still have the same level of disambiguation.  Why would someone be
unwilling to sign the one, but willing to sign the other?

Yes, a key without any UID containing an email address is of
questionable usefulness.  Agreed.

But if they can only prove one part of the data to their satisfaction,
why should they not sign only that part?

"In communication with them" is not good enough for the level of trust
that these checks imply.  Besides, the scenario I described already
implies that they must be in communication.

But it's really irrelevant to the original point, which is that in many
cases, the real name doesn't matter; only the email address/key does.
"If I know a person only by email, then that email *is* the person to
me."  In that case, if the email is trusted, then the name on the UID is
irrelevant.  I might be willing to trust that key ID 0x99242560 really
is used by the holder of email dshaw at, but not that the
person in question really is named David Shaw. ... and in most cases, I
probably don't really care about the real name of the keyholder, only
about the email address.  So why should I have to sign both in order to
declare this trust?
Bad - You get pulled over for doing 90 in a school zone and you're drunk
off your ass again at three in the afternoon.
Worse - The cop is drunk too, and he's a mean drunk.
FUCK! - A mean drunk that's actually a swarm of semi-sentient
flesh-eating beetles.
