Cool.

Yes, it seemed like a great suggestion until I tried to construct in
my mind a way in which it would be useful. (I think the idea occurred
to me when I was reading the discussion about whether GnuPG logging
how often I received emails from a particular sender was problematic.)



Another thought. New signatures from a key that has long been inactive
may arouse suspicion. Perhaps it would be useful to output how long
ago was the last message verified. For example:-

"66 messages signed over the past 3 years. The last was 1 year 10
months ago."

Always be on the lookout for conspicuousness
