i noticed lots of users pgp-sign their mails to mailing-lists. what exactly is the reason/usecase/attackvector you defend against for that? what exactly is the reason for doing so on public mailing lists? and why does it make sense to sign irrelevant messages like "+1" or "just kidding" - assuming no stego usecase is in play.
One more reason: spreading the word about GPG/PGP. This actually helps get people interested in encryption, and helps also inform people that do have a GPG/PGP key (but for different reasons do not use them on a general basis), that here's a person that does use it, and it's possible to encrypt e-mails to that person.
Which might not be all that important on cpunks, I give you that, but a rule is a rule. ;)
I do it to let the people I am communicating with through plaintext email know that I am setup and configured to handle encrypted communications. All they need to do is pull my pub key off of a key server and then our communications are encrypted from that point forward. The prevention of being impersonated is also one reason, along with a way to secretly signal to the recipient that I am under duress and my words may not be my own. Course that all goes out the window when emailing from my cellphone. That ain’t no way I want my private key on my cellphone.
