Much has been written about internet networking: facebook, twitter and the like. I'm just going to add my bit.
Facebook is like one big gossipfest. Useful, but also designed to make those not 'in' feel 'out'. It's particularly bad for teenagers - facebook promotes the one-upmanship and putdowns which so many suffer from.
That makes me angry. Life is difficult enough in adolescence. Why can't people just be NICE, REAL and HONEST?
There we are. I've said my bit.
