Is Facebook an addictive site, an invasion of privacy, or simply a neat way to stay in touch? A recent article in the New York Times says people are leaving. See http://www.nytimes.com/2009/08/30/magazine/30FOB-medium-t.html?_r=2
I do not believe it is perfect and one must use it carefully. A Canadian court ruled that Facebook must remove all you information when you quit facebook. Facebook says they will comply but it will take several months for them to change.
I find it a neat way to stay in touch with some people whom I would not normally keep in contact. One of my cousins and her family was over the top on her use of facebook and suddenly removed herself. I think she was one of these addicted people.
One difficulty I think is if I comment on a picture of someone on my network, everybody on my network can see the pictures of that person. That makes me a little uncomfortable. However I think we should accept as reality that our posting may not be very private. Awareness of this fact helps me manage how I use it.
I am still a participant but am not addicted to it. Caution is really important.
Anybody have an opinion on Linkedin?
