The next generation of viral marketers is educated. What is facinating to me is that I remember hearing about a similar meme (“hi, we’re a 6th grade class from a flyover state, send this email as far as you can!”) happening a couple of years ago, and generating so much traffic to the school’s email server that their service provider pulled the plug (archived at snopes)
What is it about 6th graders that makes them just oh-so-irresistable? This is definitely unexplored memetic territory. Who’s more virulent, 3rd graders, or 6th graders? An orphanage from a third world country?
