Well theres nothing to suggest that they don't get stronger either. As for knowledge there is only one that I can think of that would have more knowledge than the ancient jedi and sith and that would be Yoda. I mean 850 years of experience has got to make him one of the greatest force users that ever lived.
Uh, the Force ghosts live in solitude, unable to feed their minds. Ever seen someone who was locked in say, solitary confinement for years on end? They're bats, their muscles atrophy, their brain has died not being able to be used. Just imagine the atrophy of a spirit that cannot feed its persona with any kind of stimulation or information, and cannot study or perfect techniques. Exar Kun's spirit was mad. Ajunta Pall's spirit was confused, having lost memories over the years. Obviously all that isloation takes its toll on them. I thought it was pretty obvious, but apparently it's not.
