Today’s so-called social media, including Facebook, Twitter, and others, are simple electronic walls for timid, weaklings to hide behind.
Each function promotes anti-social behavior. This phenomenon of our times is a phenomenon analogous to the mid-1970s’ craze and infatuation with CB radio. That craze passed and is not notable except in this type of context. But it is not likely that social media will waste away to nothing.
Understand that social media is only what it appears to be: A place for lonely, self-involved people to waste time. Social media will survive because there are myriads of lonely people with a lot of time to waste and each has easy access to numerous access points.
OK, so you do some actual productive communicating for work and social good. When anti-social media dissolves away, you will find and use other effective methods to accomplish more.
