Facebook has over half a billion users. Almost everyone I know uses it. I use it. You probably use it. But ubiquity isn’t equal to universality. Everyone knows one of those self righteous Facebook abstainers. Social media luddites. Pushing aside modern society in favor of a purer lifestyle, devoid of pokes, tags, and feeds. Defenders of something more natural andindependent than Zuckerberg’s friendship hive.
