Just As the proliferation of fast food produced the "slow food" movement in the 1980s, and thespread of reality television inspired "slow TV" in the early 2000s, the constant buzzing of smartphoneswith notifications, messages, tweets and posts will, in 2019, give rise to "slow social". It has startedalready. (46)Where once social networks did everything possible to make their services "frictionless",
making it easy to share or forward posts and messages, they have begun, gingerly, to apply the brakes.
(47) In July WhatsApp put a limit on the number of people or groups to whom a single message can be forwarded in one go. Instagram, a photo-sharing app, introduced a "You're all caught up"feature, which reminds users that they have "seen all new posts from the past two days" and shouldreally go and do something else. Facebook launched a feature that allows people to check how much timethey are wasting on the social network, and to snooze notifications for a period. (48)And in SeptemberTwitter announced that it would allow its users to go back to its older timeline, in which tweets arevisible in simple reverse chronological order, rather than organized by an algorithm to maximise the timespent using the service.
If these changes work, and as others follow, social networks will find that their holy metric of"engagement"--how much time people spend on their services--may decline. (49)But slowing thingsdown, even if it also means slowing their own growth, is a good way to keep users happy in the longerterm and avoid blame for viral misinformation and hate speech.
Twitter's algorithmic timeline helped things go viral more easily. So did WhatsApp's easy-forwardingfeatures. Erecting barriers to virality is perhaps the fairest way for social networks to deal with theproblem of misinformation without having to become arbiters of truth. (50) Facebook, which ownsInstagram and Whats App, says it wants the time people spend on its networks to be "intentional,positive and inspiring". That is an acknowledgment that constant screen time is having a detrimentaleffect on users. Facebook would rather its users moderated their intake of polarising opinions and holidaysnaps than burn out and quit.
The new time-counting features are akin to road signs and rest stops on the informationsuperhighway. Expect to see more signs, and speed bumps, in 2019.
