The argument for pgp signing your emails is that it makes it harder for others to spoof your email address.

If I send you an email signed with my private key and the public version of my key is a place where your email client can access it, your email client can validate that the email originated from me.

Lucky you that you've never had your email address harvested from a public list and then used to spam lots of people...

All I've ever heard about PGP signing emails is "Don't", even from the
PGP creator, supposedly. But maybe I'm wrong and someone giving a
good presentation (any CS classes on security who would be interested
in joining for this talk?) would be nice.

I've never found a personal need for this myself.
