Social media

Which platforms, and how they are used

Which social media platform someone uses tells you something real about their world: the apps that dominate in one country can be virtually absent in another, and the norms around how to use them differ just as sharply.

Social media is not one global culture with local accents. Different platforms dominate in different regions, for reasons that mix technology, regulation, language, and network effects. WeChat and Weibo are central to everyday life in China in ways that go far beyond what Western social apps do (payments, ID, work, health tracking). WhatsApp is the default messaging layer across large parts of Africa, Latin America, South Asia, and the Middle East. LINE dominates Japan and parts of Southeast Asia. KakaoTalk is deeply embedded in Korean social life. Instagram, TikTok, and Facebook each have very different demographics and cultural meanings even in markets where they coexist.

Beyond which platform, how people use social media differs enormously. In some cultures, social media is very public and performative, oriented toward broadcasting identity. In others, private group chats and closed communities are the real social life, and public posting is rare or considered show-offy. Norms around what to share (family life, food, opinions, grief, politics) vary widely. The relationship between online and offline identity is calibrated differently across contexts, with real consequences for how you are read if you do not know the local rules.

How it varies across cultures

The same facet, lived differently. These are tendencies and illustrations, not rules, and never a ranking.

Platform dominance by region

WhatsApp is the primary messaging tool across much of Sub-Saharan Africa, India, Brazil, and Southern Europe. In China, WeChat handles the same role plus much more. In South Korea, KakaoTalk dominates. In Japan, LINE is the default. North American and Northern European contexts rely more heavily on iMessage, SMS, and Instagram DMs.

Public vs. private orientation

In many East Asian contexts, public social media is used more carefully and with greater attention to group norms, while private messaging groups carry more candid social life. In contrast, many Northern European and North American users treat public posting as a more natural extension of self-expression.

Professional and personal mixing

LinkedIn is used as a professional network in many Western contexts. In others, professional networking happens via WhatsApp groups, Facebook, or entirely outside social media. The expectation that work and personal social presence should be kept separate is far from universal.

Political use of social media

How social media intersects with political speech varies significantly: from contexts where political posting is normal and expected, to contexts where it is actively suppressed, to contexts where political life happens in pseudonymous or highly coded ways.

Questions to explore

Use these on your own or in a group. There are no right answers, only better conversations.

Which platforms do you actually use for different parts of your social life, and how did you end up there rather than somewhere else?
What are the unwritten rules in your culture about what you share publicly on social media versus what stays in private groups?
How does it feel to enter a social context where the dominant platform is one you barely use or have never used?
What do you think social media reveals about a culture, and what does it hide or distort?
How do you build or maintain trust with someone whose social media habits are completely different from yours?

Things to notice

Defaulting to Western platform assumptions: in many parts of the world, Facebook, Instagram, and X are not the main channels, and assuming they are can signal a significant blind spot.
Confusing platform absence with social media absence: someone who is not on Instagram may be extremely active on WhatsApp, Telegram, or a platform you have never used.
Misreading silence as disengagement: in cultures with strong norms around public caution or privacy, low public posting activity often coexists with very rich private social media life.
