Keep the PGP-key without password and store it on a crypted
filesystem. That way, at least when you are the only user &
sysadmin of your computer, you only have to write a key once
per session, and you can feel pretty safe about it. (Assuming
that you notice if the system has been tampered with.) The same
goes for SSH-keys, etc.

Well, this kind of programs seem to be behind the motivation
for Wassenaar Agreement & US lobbying efforts, so I imagine
they give them spooks severe headaches, and that makes this
worth while for me.

Also, keeping a seemingly interesting mailinglist that is open
only to people who can and do use PGP, would seem to be helping
in proliferating it's use to the masses.

PS The PGPdomo doesn't seem to be very widely available at the moment.
(I couldn't find it.) So, I think some mirrors would be helpful.
