It is strange seeing so much angst (maybe that's a bit strong) or concern over yet another brain dead time wasting life wasting game. Sure, we cannot, and indeed would not want to impose any sort of intellectual requirements on individuals but if anyone remembers the original iPad intro there were life affirming images of them being used as tools for knowledge that was formerly presented in such a way as to be virtually inaccessible to people without high levels of training.
If ones takes a step back from the world and looks at the brain deadening influence and reach of facebook and twitter it would seem that the world is heading in a direction of producing a general population of faceless twits.
Wake up and smell the coffee, then perhaps ruminate on the molecules that drift into the receptor neurones and how an electric potential is delivered to and rerouted to maybe thousands of synapses and somehow, some sort of "I" has a sensation of what this smell means. Or not. But at least one would hope that the possibility to do this is one of choice and not because people have become so dumbed down as to think this very post is just annoying or threatening.
