Other Forms
The kind of mindless Internet advocacy Upworthy's been accused of promoting has inspired a new word: clicktivism. Clicktivists mistake gratification for meaning. They conflate feeling good (or self-satisfied or inspired or righteously indignant) with doing good. They watch a video of a kid sharing his lunch with another kid, forward it to their social networks or sign a petition, congratulate themselves on their political involvement, close the browser window, and diminish the definition of service for everyone.
