Honestly, all of these "I refuse to use social media!" type articles just remind me of people who spam "all the music of this generation sucks; I'm 14 and I was born in the wrong generation" on YouTube videos.
Going against the mainstream often is a package deal that comes bundled with a superiority complex against people who choose to engage in the activity that you choose not to engage in.
I saw a comment in this very HN thread that goes so far as to say that youth who use social media display "intellectual vulnerability," and that _not_ using social media is an asset warranting immediate hire.
Social media exists as a way to facilitate communication online over a long-distance, i.e. old friends who now live in different places. Problems that we think are "unique" to social media, like the loudest, wrongest voices getting the most attention, exist in human society outside of social media as well. It's not an exclusive phenomenon.
Of course, not everybody has to use social media.
But you're not a special snowflake just because you don't have an app installed on your phone...
