Food for thought.
“Social media has, in effect, brought back public shaming, the kind of rough justice that occurred before the modern age, or may still occur in places where law enforcement is felt to be ineffective and vigilante groups enforce community norms without any formally constituted legal authority.”

The chapter from which the above quote comes – The Return of Public Shaming – analyzes the topic with (unsurprisingly) the moral clarity expected of Sacks. Reading the whole book is like watching a top-of-the-range fireworks display of observation, analysis, and moral leadership. Energetically infused perspectives and ideas popping off the page every paragraph or so. Highly recommended.
