Ah!  PGP...  Few do that (that I see).

For the most part, it's a waste of time.  Unless you've collected a
signature *directly* from me, there's little confidence that someone
saying that they're me, even if signed, is me.

There's a tiny bit of confidence when someone else has vouched for me,
and countersigned.  But how many of them really check?

There's virtually no confidence in signatures from PGP servers, as far
as I can see, unless they're countersigned by various people that I
would know or trust.  And I really don't know anyone on this list. 
I've never met any of them.  And if you did, could you tell a real
ID from a fake ID if they tried to prove they were who they said they
were?

I also found that PGP servers were a major source of spam.  Any time
you uploaded a key, somebody harvested it and spammed me, straight
away.  I could test this by creating extra keys and uploading them,
they'd get harvested and spammed in minutes.

If you're talking about body text, everyone else has their style.  Some
have a stack of intro lines like:

last person said:
> second to last person wrote:
>> third to last person posted:

Which gets messy real quick.  I try to limit replies to quoting no more
than two people if it makes the message more coherent than just one
person's last comments.  And try to allow newspaper style editing - you
can slice off everything above and below the bits you're concerned
with, in huge slabs, you don't have to hunt and peck through.

And again, I think you may be seeing something like your mail program
hiding quoted text, even signatures (the textual boilerplates, not PGP
signing).  If I look on the mail archive, it's definitely doing that
(which probably explains why a lot of people put zero effort into
trimming their replies).  If you click on the (...) on the webpage you
can expand the hidden text, but that makes for laborious reading of
messages.

As a comparison, have a look through your menus for "view source" and
see what a message looks like before Thunderbird converts it into its
own HTML rendition of the message (regardless of whether it was HTML or
plain text).

Thunderbirds re-rendering of messages is yet another reason that
I don't like it.

That's already been explained that a few times.

To be honest, you can't trust any "from" address as being real.  Anyone
can fake the headers, few things verify them, and there's still plenty
of mail servers that don't verify that you are who you say you are
before accepting a post.  The SMTP servers that I use do require my
mail program to log-in when posting, and my from address has to match,
but there's more to it than just that.
