What really bothers me about this article is that at no point are there actually any eight year-olds. It's one thing to say "An eight year-old could understand this", and another to have a loose transcript of an actual conversation, à la "Explaining REST to my Wife" ( http://tomayko.com/writings/rest-to-my-wife http://tomayko.com/writings/rest-to-my-wife ) or "The Socratic Method", where the author teaches binary to third graders ( http://www.garlikov.com/Soc_Meth.html http://www.garlikov.com/Soc_Meth.html )
