A Different Kind of Social Space
The Fediverse didn't emerge from a Silicon Valley growth strategy. It was built by communities who explicitly wanted something different from mainstream social media — less algorithmic manipulation, more genuine human connection, and spaces where thoughtfulness is rewarded over virality. That origin shapes everything about the culture you'll encounter here.
Knowing a few key norms will help you fit in, make friends, and avoid unintentional missteps when you're getting started.
The #Introduction Post: Start Here
When you create a new account on the Fediverse — particularly Mastodon — the very first thing you're encouraged to do is write an #introduction post. This is a public post where you introduce yourself: who you are, what you're interested in, what you plan to post about.
Use the #introduction hashtag. People actively search this tag to find new folks to follow. Be genuine, be specific about your interests, and don't be shy — the community is usually quite welcoming to newcomers who make the effort.
Content Warnings: Use Them Generously
One of the most distinctive features of Fediverse culture is the widespread use of Content Warnings (CWs). A CW hides the body of a post behind a clickable label, letting users choose whether to read further.
CWs aren't just for extreme content. Common uses include:
- Politics and current events — Even mild political discussion is often CW'd out of respect for people who need a break.
- Mental health topics — Posts about depression, anxiety, or difficult personal experiences.
- Food and body image — Out of consideration for people with eating disorders.
- Eye contact in photos — Some users, particularly autistic folks, prefer a warning before seeing direct eye contact.
- Spoilers — Film, TV, book, and game spoilers are almost universally CW'd.
- Long threads or rants — Letting people opt in to longer reads.
CW culture isn't about censorship — it's about consent and creating a considerate space. When in doubt, use one.
Boosting vs. Quoting
On Mastodon, sharing someone else's post is called boosting (equivalent to a retweet). The Fediverse has traditionally been cautious about "quote posting" — sharing someone's post with your own commentary attached — because it can be used to direct harassment at someone from a larger audience.
Some instances and platforms (like Misskey) support quote posts, but the cultural norm is to be thoughtful about how and why you use them. If you want to respond to someone's post publicly, a plain reply is almost always more appropriate than a callout-style quote.
Alt Text for Images: It's Expected
Providing alt text descriptions for images is taken seriously in Fediverse communities. It makes content accessible to people using screen readers and those with visual impairments. Many users will politely ask you to add alt text if you forget, and some even use bots that automatically remind posters.
Take a moment to describe what's in the image when you post one. It becomes second nature quickly.
Don't Cross-Post Without Thinking
Many newcomers set up automatic cross-posting from Twitter/X or other platforms to Mastodon. While the tools exist, the community generally has mixed feelings about it — especially if the cross-posted content is full of Twitter-specific references, @mentions that don't resolve, or broken links.
If you cross-post, make sure the content makes sense in the Fediverse context. Manually curated cross-posting tends to be received better than fully automated feeds.
Engage, Don't Just Broadcast
The Fediverse doesn't have an algorithm pushing your content to strangers. Growth here is organic and relationship-based. Reply to people, have conversations, boost others' good posts, and be genuinely present. The community rewards authenticity over performance.
You may notice follower counts matter less here than on other platforms. That's intentional. The emphasis is on the quality of interaction, not the size of your audience.
Respect Instance Rules
Every instance has its own rules. Read them. What's acceptable on one instance might lead to a ban on another. Instance admins can also choose to defederate (block) other servers that violate their values — so the norms of your instance affect what you can see and interact with across the Fediverse.
If you find yourself frequently at odds with your instance's culture or rules, it might be worth exploring whether a different instance is a better fit. Migration is supported and not as painful as it sounds.
