A journalist recalls how in the past, the worst feedback one could receive for an article was a letter from an angry reader. However, a misplaced tweet can now have a much greater impact due to social media. The author's friend had once fabricated a local knitting group for filler content in the newspaper, which resulted in numerous real letters inquiring about joining. Nowadays, as shown in Jon Ronson's book, people's lives and mental health can be ruined by a single imprudent tweet being spread widely. Celebrities are also constantly harassed online by trolls. The author notes experiencing this firsthand when a photo of them was tweeted to an actor's many followers as a joke.
