What i have learned is that i use with my (online) friends a separate
list with their name and fingerprint on, have let TOFU checked the
first couple of messages and then give them full trust with TOFU.
Since i have those contacts only sometimes, i think it's a good
procedure comparing a Good Signature's fingerprint on my monitor
with one from a paper list. (a copy of the paper list is also hidden
in a another place)
