Young adults are rapidly reshaping how they use social networking services (SNS).
The era of staging a flawless life for a broad, anonymous audience is fading. Instead, “narrow and deep” communication — sharing small moments with only a few close contacts — has become the norm. Young people are shedding the fatigue of meticulously editing photos and polishing captions for public display and are choosing to share raw, unvarnished slices of daily life. In this shift, the ultra-short video app Setlog has emerged as a new hangout for people in their 20s and 30s.
Data from Naver Data Lab show searches for the term Setlog rose from about 10,000 in November last year to more than 80,000 by March. The app also topped the App Store’s free charts, underscoring growing interest. We examined why this format — brief, 2- to 3-second clips that check in without flashy filters or staging — has captured young users.
Young adults tired of performative life… seeking a safe space
Setlog’s operation is straightforward. Friends or family create a private room, and the app sends notifications at set times. Users record roughly two seconds of whatever they’re doing and post it. Only people in the room can view the clips, comment or react. After 24 hours, those fragments automatically stitch together into a daily vlog.
Users say the chief benefit is relief from social pressure. On platforms like Instagram, where followers can number in the hundreds or thousands, every post invites scrutiny. Setlog’s closed structure limits audiences to approved contacts. Office worker Shin, who uses the app with his sister, said it offers psychological ease. As his follower count grew, posting felt like a burden; Setlog, he said, functions like a refuge where he can communicate without polish.
Close even when far away… efficient relationship upkeep
The app also helps people maintain bonds with friends who live far apart.
Setlog’s appeal lies in its ability to let users peek into friends’ days in real time, even when their work lives are worlds apart. Different schedules used to make it easy to lose touch. On this app, a reporter racing to meet a deadline, a firefighter waiting for a call, and a police officer taking a short break in a patrol car can share their three seconds in the same room.
The image of a reporter’s fingers clacking on a keyboard, a firefighter wiping sweat beside turnout gear, or a police officer’s radio crackling in the background conveys a long day without lengthy explanation. Users say that, though they live in different worlds, watching those timed, three-second clips together reassures them that everyone is doing their best — and that shared sense of effort often forges a stronger bond than long conversations.
You can post a single clip to multiple groups at once, saving time. Without messaging everyone individually, you can catch what a friend had for lunch or what the evening sky looked like and keep the thread of connection alive. It reflects a younger generation’s preference to manage relationships efficiently amid busy lives.
The app’s feature that compiles clips by time to close out the day also gives users a sense of accomplishment. Without extra editing, the day you shared becomes a video diary before sleep — an appealing alternative to a perfectly staged highlight reel and aligned with today’s taste for modest, authentic records.
Fatigue from comparison… a return to closed communication
Experts view the trend as a reaction against social media’s relentless comparison culture. They note younger users are exhausted by overexposure to an anonymous mass audience. To escape the self-doubt that comes from measuring themselves against others’ highlight reels, people are choosing spaces that bring together only like-minded friends.
Short, immersive videos — more so than text or photos — have become a glue for communities of shared taste. The three-second length provides visual stimulation without the viewing burden of longer clips, making it an optimal point for casual, frequent communication.
This dynamic appears across popular culture. The challenge trend for AKMU’s new song “Paradise of Rumors” has spread among people in their 20s and 30s for similar reasons: participants fold small moments of daily life into short clips rather than showing off polished dance skills. It signals that empathetic, consoling interactions are displacing one-upmanship.
Low‑power communication favored by digital natives
Ultimately, Setlog’s popularity shows that generations raised in a digital environment have developed their own survival strategies. Faced with an overload of information and connections, they’re narrowing who they connect with and dialing down the intensity of interaction. Rather than energy‑intensive, high‑power communication, they’re filling emotional gaps with short, light, low‑power exchanges.
That closed, immediate mode of communication is likely to strengthen. We’re entering an era that values authentic daily life shared with people who genuinely care over performative records meant to impress. The current SNS trend is better captured not by an influencer’s glossy feed but by young people laughing at a friend’s three‑second yawn clip.
