It would be easy for me to sit here and tell you, "Quality is more important than quantity." So let me put it this way.
I just asked my 17 year old daughter, a "Myspace" veteran, how many of her 160 contacts she actually considers "friends."
Her answer, "About 20."
My hunch is that collecting friends on spacebook is more a matter of time than popularity. Many casual contacts stay there because the myspace owner feels reluctant to "delete" them. "Deleting" a friend sounds so harsh.
Quality friendship takes time and effort. You sound intelligent and thoughtful. Give it time. You are not a loser, just a newbie.
