A while back, at dinner, I explained to a friend about the service Twitter and he just could not get his head around it. He kept asking why would anyone want to know the day to day minutia of what happens in everyone's life. I understood why he was having trouble with it but for the life of me I could not think of way to explain it better. So as usual commoncraft has come to my rescue. I have posted about them before. They did a terrific job explaining this service. Give it a try.
