^You know your social circle is too small when...
   .... you have to be careful WHO you click Like on and WHAT you
   click Like on 'cause you might lose favor with the social
   circle...

   Like what you like, not only what your group likes. Of course,
   this ALL changes if your Great-Aunt is an active Facebooker...
   next Thanksgiving - WATCH OUT! "Psst - did you see that
   so-and-so Liked such and such? OMG", says the great-Auntie, hip
   with the ways of modern gossip...^
