Thank you Josh and Mike. A fascinating conversation that has given me food for thought. For me until now I had simply taken things as read within my quick google search for a possible answer. I will certainly consider further the answers that I receive and delve deeper as oppose to taking the initaly feedback at face value. In addition to this your fab discussion was poignant mor over the hold it has on those that use it. For some it is their only link to the world because they have little else, for others it is a place to gossip and for some a way to stay in touch. It is however driven by people which worryingly gives it great power.
