This is a fascinating look at a problem that is as old as the human race. Well-written. :) Btw, I once was deidrecorwyn, and we were mutual friends. I am now a_blue_moon_cat and when I applied the rename token, LJ went wonky on me and I lost all my mutual friends. I am still a friend of yours, but I will need you to please friend me back. Thanks in advance. :)
