I have successfully shunned social networking(twitter, faceboook, etc) to this point although I am on LinkedIn for professional reasons. I find it boring and pointless to share my life with strangers and I keep up with my family the old fashioned way; face to face or pick up the phone and call them.
I do see advantages to social networking when the participants have some thing like sailing in common.
BTW, aeventyr60, Sailnet is a form of social networking and your response smacks of hypocrisy.
