Some social web sites are only slightly social. Their main function is to help you organize stuff - your schedule, your thoughts, your posessions, and your experiences.
However, I joioned one recently that is a pretty nice social network. It let me get back in communication with people I had lost touch with over a decade and a half ago.
These were people I used to see practically every day. Some weeks, I did see some of them every day!
it is not unusual to find a program that is useful or fun to use. However, this particular web site I am actually grateful too.
