I strongly disagree with this. Users are just responding to dopamine sensors that have triggers that they don't understand. "Value" extracted can be detrimental to a person's well-being, even if they chose it for themselves. Gambling addicts at casinos, obese people at fast food restaurants, pay-to-win whales and the newest version of Candy Crush. Reddit is just a casino where you gamble with your time and win addicting emotions like novelty and outrage.
