ADDED: I received email from a man whose 18-year-old son died in an accident:
Because he graduated from high school in June, most of his friends are also college freshmen, and in September were newly scattered to the four winds, nowhere near their closest friends and not yet having developed close friendships in their new schools.... [They] posted hundreds of messages to his wall in the weeks following his death, and they continue to post there. These comments have brought, and bring, considerable solace to them, and to my wife, our daughter, and me.
And it was through Facebook that we were able to arrange with [his] friends all over North America to offer a tribute to him when they were home for Thanksgiving. We used Facebook to put out a call for ideas, and his friends used it to get together over long distances and decide how to pay tribute....
So now I have a use for Facebook, and I have more respect for its role in life and society than I ever thought I might. It can be a useful thing, and can bring comfort. To my surprise, it can bring people together and sustain them though emotional turbulence. From our family's vantage point at least, the benefits of Facebook outweigh whatever deleterious side-effects it might have.
