Summary
Key Findings
Instance Loyalty
Identity MarkersUsers strongly identify with their local instance's culture and rules, often favoring it over the wider network, creating loyalty to specific communities rather than the platform as a whole.
Transparent Governance
Social NormsInstances emphasize open, democratic moderation and governance, making rule-setting a collective, visible process that contrasts with opaque centralized platforms.
Content Warning Norms
Social NormsStrict, community-enforced content warning etiquettes are expected; failing to use content warnings properly can lead to swift social sanctions.
Federation Complexity
Communication PatternsCommunication across instances involves nuanced federation dynamics—users must navigate diverse rules and blocklists, understanding that cross-instance relations shape information flow and social bridges.

Facts & Sayings
„Toot“
The Mastodon equivalent of a 'tweet'; a short post made by a user on the platform.
„Boost“
Similar to a 'retweet,' a boost shares someone else's toot with your followers, amplifying the message.
„Fediverse“
A portmanteau of 'federated' and 'universe,' referring to the network of interconnected decentralized social platforms including Mastodon.
„Instance“
A single Mastodon server with its own community, rules, and culture; users choose an instance to join rather than one central platform.
„Content Warning (CW)“
A feature that hides sensitive or potentially disturbing content behind a warning label, respecting community standards for safety and comfort.
Unwritten Rules
Always respect instance-specific rules and culture.
Each Mastodon instance has its own guidelines; abiding by these is critical to maintain trust and avoid conflicts within that community.
Use content warnings thoughtfully.
Applying a CW to sensitive content signals respect for others' boundaries and enhances collective safety on the platform.
Boosts should be meaningful.
Boosting is an endorsement; indiscriminate boosts can dilute conversations and annoy fellow users.
Introduce yourself when joining a new instance.
The hashtag #IntroduceYourself is widely used to warmly welcome newcomers and encourage integration into the local community.
Avoid posting overly commercial or self-promotional content without context.
Many Mastodon communities value authentic interaction over advertising; unsolicited promotion can be seen as intrusive.

First Steps & Resources
Get-Started Steps
Time to basics: 1-2 weeks
1
Research Mastodon Instances
1-2 hoursBasic
Summary: Explore different Mastodon servers to find one that matches your interests and values.
Details: Mastodon is a federated platform, meaning it consists of many independently run servers (instances) with their own cultures, rules, and focuses. Before joining, spend time researching various instances to find one that aligns with your interests, language, and moderation style. Visit instance directories, read about their community guidelines, and browse public timelines to get a feel for the atmosphere. This step is crucial because your choice of instance shapes your initial experience and connections. Beginners often rush this step and end up on servers that don't fit their needs, leading to frustration. Take notes on what matters to you—topic focus, moderation approach, or community size. Evaluate your progress by identifying at least two or three instances that genuinely appeal to you and understanding their unique characteristics.
2
Create and Personalize Account
30-60 minutesBasic
Summary: Sign up on your chosen instance, set up your profile, and write an introductory post.
Details: Once you've selected an instance, register for an account. Fill out your profile with a bio, avatar, and header image that reflect your interests and personality. Craft an introductory post (often tagged #introduction) to let others know who you are and what you hope to find or contribute. Personalizing your profile helps you stand out and signals your intent to participate meaningfully. Many beginners skip the intro post or leave profiles blank, which can limit engagement. Take time to read other introductions for inspiration. This step is important for building initial connections and establishing your presence. You can gauge progress by receiving welcomes, follows, or replies from other users.
3
Engage in Local and Federated Timelines
2-3 days (ongoing)Intermediate
Summary: Browse, like, boost, and reply to posts in both local and federated timelines to join conversations.
Details: Mastodon offers two main timelines: the local timeline (posts from your instance) and the federated timeline (posts from across the network). Spend time reading, liking, boosting (sharing), and replying to posts in both. This helps you understand the culture, discover interesting users, and start building relationships. Beginners sometimes lurk too long or only interact with a narrow group, missing out on the platform's diversity. Don't be afraid to join conversations, ask questions, or share your thoughts. Use hashtags to find topics you care about. This step is vital for integrating into the community and learning the platform's norms. Progress can be measured by the number of interactions you have and the connections you start to form.

4
Learn and Respect Community Norms
1-2 hoursIntermediate
Summary: Familiarize yourself with instance rules, content warnings, and moderation practices to participate respectfully.
Details: Each Mastodon instance has its own code of conduct, moderation policies, and expectations around content warnings (CWs) and sensitive media. Carefully read your instance's rules and observe how others use CWs for topics like politics, spoilers, or sensitive content. Beginners often overlook these norms, leading to misunderstandings or moderation actions. If unsure, ask moderators or experienced users for clarification. Practice using CWs and tagging content appropriately. This step is crucial for maintaining a positive reputation and avoiding accidental rule violations. Evaluate your progress by confidently posting with proper warnings and receiving positive feedback or no moderation issues.
5
Participate in Community Events
1-2 weeks (ongoing)Intermediate
Summary: Join hashtag games, themed discussions, or collaborative projects to deepen your engagement and visibility.
Details: Mastodon communities often organize events like hashtag games, themed discussion days, or collaborative art and writing projects. Look for announcements in your local timeline or via popular hashtags. Participating in these events is a great way to meet new people, showcase your interests, and become part of the community's fabric. Beginners sometimes hesitate to join in, fearing they're outsiders, but these events are designed to be welcoming. Start by observing, then contribute a post or two. This step helps you move from passive user to active participant, building lasting connections. Progress is evident when you receive replies, boosts, or invitations to future events.
Welcoming Practices
„#IntroduceYourself hashtag“
New users post using this tag to share about themselves and signal their arrival, which hosts and members often respond to with welcoming messages, fostering a friendly onboarding experience.
„Moderator greetings“

Misconceptions
Misconception #1
Mastodon is a single social media site like Twitter.
Reality
Mastodon is actually a network of independent servers ('instances') that interoperate via the ActivityPub protocol, each with its own culture and moderation rules.
Misconception #2
Content warnings mean the community is overly sensitive or censorious.
Reality
Content warnings are used consensually to respect personal boundaries and create safe spaces, not to impose censorship; they empower users to choose what content they see.
Misconception #3
Mastodon is only for tech experts or niche activists.
Reality
While many users have technical backgrounds, the community is diverse, including casual users, artists, writers, and people from many walks of life seeking better online interactions.
Clothing & Styles
Fedora or Beanie (informal)
While there is no official dress code, some users jokingly associate certain hats like fedoras or beanies with tech-savvy or activist identities within the community, symbolizing a casual yet thoughtful attitude.
