The Avatar was also the name of folk musician Mel Lyman's rag. So folkies have been using & understanding that term for over a 1/4 century now. I used to get copies every now & then, growing up in the vicinty of Fort Hill.

Obama being a Harvard scholor, I'm sure was also familar with the term & maybe the rag too.

Obama hasn't tried to cover up his education at all, if anything he's used it as an example of some of the pros & cons of our educational system. Pro being that loans are possible & con that it's not as accessable to the poor as it is to the rich
