I'm starting to feel rather stupid now, like a fairly intelligent
bloke such as myself _should_ grok this model without even blinking. I
wonder, then, how Joe Luser then is expected to understand a word of
it, especially given an assumed very low interest in technical matters
Anyway, I digress.
I am failing to see a couple of things here. Signatures are the glue
of the web of trust model, and trust is calculated on a per-key basis,
not on a per-ID basis. Then what is the point in signing IDs? But on
the other hand, if there's no signing on a per-ID basis, then, after
getting a number of signatures, someone might create bogus IDs.
I don't think that I'm mixing up trust and signatures here... but who
knows? Signatures should be all about verifying people's identities,
but in creating a new ID, how do I avoid having to have that
particular signed all over again? Needless to say, pulling keys out
of the web of trust is a Bad Thing(tm), but that doesn't seem to be
the argument that most people make when they tell you to make a new ID
rather than a new key. The current system makes relatively good sense,
but to me it doesn't seem to make _perfect_ sense. ARGH!
 I guess that once someone has signed your key once, and therefore
should trust that you are who you say you are, then, because they
trust your key, they'll not be reluctant to sign a reasonable new ID.
