Social media is a curious thing. On the one hand, it offers an endless parade of ephemera from the daily lives of friends, family, and strangers—discussions of a fondness for yogurt, a picture of a barista’s decoration in latte foam, descriptions of excellent meals, pictures of pets and small children or maybe an abandoned easy chair on a crowded street corner. There’s all manner of self-promotion and relentless affirmation. There are knee-jerk, ill-informed reactions to, well, everything. The abundance of triviality is as hypnotic as it is repulsive.
