Forget the telephone or email, we now seem to demand to know what are friends are doing from one day to the next. No idea why, but people do not seem to value anonymity with their social network. There's a need to show their friends the photos from their night out. Fine if you're 19; not so mature when you're 29. Still, social networking is very popular. So popular that it's almost impossible to bring all your friends and family together within one network.12 Nov 2008
