@33mhz Encrypt/sign as much as possible, I think. I'm setting up my email client to sign all outbound email (just from the desktop for now) with my public key. Uploaded it to a public keyserver so it can be verified.
My public key fingerprint is 971D6E55, and I've uploaded it to the GnuPG keyserver. Looks like just a couple of the folks I found on Keybase have done the same, and I've signed those keys so feel special. Or something.
