​Being on social media is a study in psychology. First, there's a pecking order of social media sites. Gen X, Millennials and Baby Boomers use FB as a photo album and a stream-of-consciousness site. If you're lonely, don't know it, and want to show it, get on FB. Now, every social media platform has its own set of communities. Facebook has people who seem constantly wronged and misunderstood by their friends.
