Google Plus is like the movie Dark City. It's a group of technical aliens picking apart the human experience, trying different scenarios in order to find out what the human soul is.
Once per day, humans wake up and find themselves in its meticulously-constructed parallel universe, doing things as ordinary humans do on other websites. Their activities, such as appreciating music and searching for lovers, feel familiar, necessary and meaningful, but at the same time, the unsettling atmosphere prevents the existential questions from settling deeply repressed where they should be. Instead, we're left wondering, "Why are we doing this here?" Isn't there something better? Is there a Shell Beach out there somewhere? Couldn't I just do this all myself on 1999-style website and live a more natural life?
