Folks: To those of you who use and, worse yet, believe in the scientific validity of "outliers," I commend to you the following: http://www.sciencenews.org/view/feature/id/335383/title/Beware_the_Long_Tail If you wish to condemn or argue with me about this, PLEASE REPLY PRIVATELY, as this is waaay off topic. And my apologies to all for the distraction, but I hope you will not condemn me too harshly for taking arms against this evil dragon (in joke for those who read the article).
