Consequential strangers: An underpinning of social media?

While I don't like the title of the book (Consequential Strangers: The Power of People Who Don't Seem to Matter - But Really Do), I was compelled by the argument. "The term 'consequential strangers' captures a fascinating paradox about casual relationships: They are as vital to our well-being, growth, and day-to-day existence as family and close friends." Author Melinda Blau, interviewed by NPR's Neal Conan, explained that we may be likelier to find validation in our relationships with relative strangers than within "close" relationships. People are even likelier to accept advice on serious topics like relationships and health issues from "strangers."

This makes perfect sense to me. This is a significant part of what fuels social media. Many consider social media to be an exercise in narcissism, and it certainly can be. For me, it has often provided a way of expressing myself when calling a friend and making the same statement seems like an intrusion. Perhaps the tree wants to be heard when it falls in the forest.
