I know about the book Bowling Alone. About the huge number of Americans who are living alone and very socially isolated. I even had a suicide hotline worker tell me that the majority of people that were calling and suicidal were saying that they were completely alone in the world. In the two and a half months that I have been on Facebook I have met well let's put the word met in quotes, thousands upon thousands of people who say that they are alone in the world. Facebook is the best way to do sociological studies on any subject that you are interested in in my opinion. I am now on about, I now belong to about 200 different groups on every subject under the Sun.
