Time’s Lev Grossman counts the ways:
1. Facebook is about finding people you’ve lost track of. And, son, we’ve lost track of more people than you’ve ever met. Remember who you went to prom with junior year? See, we don’t. We’ve gone through multiple schools, jobs and marriages. Each one of those came with a complete cast of characters, most of whom we have forgotten existed. But Facebook never forgets.
2. We’re no longer bitter about high school. You’re probably still hung up on any number of petty slights, but when that person who used to call us that thing we’re not going to mention here, because it really stuck, asks us to be friends on Facebook, we happily friend that person. Because we’re all grown up now. We’re bigger than that. Or some of us are, anyway. We’re in therapy, and it’s going really well. These are just broad generalizations. Next reason.
It’s a bit comical, but you get the sense there is some truth in this. Just as when Facebook replaced Myspace, it seems that now everyone I know has migrated to Twitter. I barely log in to Facebook anymore and couldn’t tell you the last time I logged in to Myspace.
