Does Facebook have you thinking differently of your friends?

I reading some of the facebook posts of my friends and I now think very differently of them. There are some friends that I never knew were great motivators. There were some who I never knew were born again Christians. Some have made political statements. On the other hand there are some negatives I have learned about some friends. Some are a bit egotistical and with a touch of narcissism. Now I know that sounds mean but I think that what facebook and other social networks are about. Basically it is about “Hey Look At Me” or “Hey follow me”
