But the point is I have gpg now.
It's not too useful without people signing my key, but as jwz pointed out, it's not too useful in general: I don't need encryption or signatures on my email. And I have a point! I plan to use the arch patch queue manager to allow commit access to LogJam in a secure fashion for people like gaal, and that requires GPG.
And, happily, the debian-seattle-social mailing list (yes, one exists!) coincidentally has planned a keysigning party for Sunday, so I hope to get my newly-created key signed by illustrious people such as the Debian Hardware Donations Manager.
