Since this list is so weird, people talking strange (including me), no
   signatures, etc etc, it would be good to get better communications
   going.
   There are many better communication systems.
   To know your messages are meant for you by the person who claims to
   have sent them, it's really good to be able to keep a private key that
   is actually private.  This is hard for me to do.
   What device I'm on switches.  Right now my device is an android phone
   that runs very very slowly and often misbehaves.  A private key kept on
   this phone, which sometimes does things on its own while I am looking
   at it, and sometimes may wait a few minutes to respond to touching a
   button, would make security more complex.  I would barely have
   confidence that the private key was private, because I don't know how
   to make the phone behave reliably.
