My FB is an extended-family acceptable avatar of my face as it
   was with slightly shorter hair. It also has me in a serious
   pose, which makes me seem like I have a clue what I'm talking
   about.

   But my Google+ picture, where I can be myself more, is a more
   current me, superimposed within the new EARTH FLAG, showing
   myself as President of Earth for when we go out to visit the
   other planets.

   [somebody has to be president of Earth. Might as well be me
