What is Mastodon: understanding the decentralized open-source social media

Decentralized social media platforms take control and decision-making away from a central authority to individual users or communities. As people become more aware of data privacy, the demand for decentralized, open-source platforms like Mastodon is on the rise.

Mastodon emphasizes privacy, user control, and an ad-free experience, making it a popular alternative to traditional social media platforms.

In this article, we’ll discuss Mastodon’s inner workings, its standout features, and how it differs from traditional social media platforms. We’ll also discuss business use cases and explore how to use Mastodon step by step.

How Mastodon works

Mastodon is a decentralized social network run on independent servers. Mastodon users join specific servers based on their interests or values, and their profiles are hosted on them.

Mastodon servers function independently and manage their own data. Each server has its own rules, moderation policies, and community focus, so users can enjoy a variety of tailored experiences.

Despite their independence, servers are interconnected through a process called federation. This allows users on one server to interact with users on other servers, similar to how email works across different providers. These interactions create a dynamic ecosystem – the fediverse – where communities can thrive independently but remain a part of a larger network.

Seamless communication between servers is possible through standardized protocols like ActivityPub. Mastodon also uses ActivityPub as its standardized open-source protocol. So, if a third-party app or service also uses ActivityPub, it can also communicate with Mastodon, just like Mastodon servers communicate with one another.

Key features and benefits of Mastodon

Let’s have a look at what makes the Mastodon experience unique compared to other decentralized social networks.

Freedom, privacy, and security

Decentralized platforms like Mastodon provide users and businesses with greater control over their content and data. Users can manage their privacy settings, decide who can see their posts, and even run their own servers. What’s more, users actually control what content they see, with the feeds being chronological public posts from followed accounts only.

This level of control is rarely available on centralized platforms, where user data is often monetized, feeds are run by algorithms, and privacy policies change for the company’s benefit.

On Mastodon, the server moderation team sets and enforces policies that are often discussed and voted for. At the same time, users own their data and can export and delete it if they decide to leave the platform.

Customization

If you’re used to traditional social networks, you’ll find Mastodon’s user profile customization quite familiar. However, Mastodon offers some unique platform customization options.

Profile customization

  • Set a display name and a bio to introduce yourself.
  • Upload a picture to create your avatar and a header image to personalize your profile.
  • Add extra information like your website, pronouns, or location using profile metadata fields.
  • Enable profile flags to indicate locked accounts that require manual approval for new followers.

Platform customization

  • Choose between dark, light, or high-contrast themes to suit your visual preferences.
  • Minimize animations in Preferences Appearance and control the display of trending hashtags in Preferences Trends.
  • Decide between a simple one-column or an advanced multi-column layout.
  • Customize the notification settings, including email notifications.
  • Manage content warnings and set the defaults for post privacy and language.
  • Enable profile flags to indicate if an account is a bot.

Content moderation

Content moderation on Mastodon involves careful management that is typical for federated social media platforms:

  • Different servers have their own rules and moderators.
  • Clear and open moderation practices are crucial.
  • Users can participate in moderation through voting or reputation systems.
  • Servers can block or limit interactions with those that don’t meet their standards.

Ad-free experience

In a striking difference to traditional social media platforms, Mastodon’s standout benefit is its commitment to remaining ad-free. Unlike many centralized platforms that rely on advertising revenue, Mastodon is funded through donations and community support. This ad-free model has several benefits:

  • The user experience is cleaner and less cluttered.
  • User data is not tracked and sold to advertisers.
  • There’s little incentive for clickbait and sensational content, promoting more genuine interactions.

Diverse communities and culture

Mastodon’s decentralized nature encourages a rich ecosystem of diverse communities. Each server caters to specific interests, values, or demographics, allowing users to find and join communities that resonate most with them.

Some servers might focus on academic discussions, while others might be more casual. These servers often have their own culture and rules, which are reflected in the content they produce. Generally, Mastodon users understand that privacy and freedom to choose are what drive people to the platform, so these values are usually upheld.

Like many other internet communities, the fediverse has its own quirks, too. Awoo.space is one of the oldest servers on the platform, so when someone posts awoo, they’re referring to Mastodon’s early days.

In a nutshell, Mastodon fosters a collaborative and respectful environment focused on meaningful connections.

There are many advantages of using a platform based on diversity, resilience, and user empowerment, rather than algorithms and advertisers.

  • Users can choose servers with privacy policies and data protection measures that agree with their own values.
  • If the servers update their policies and these no longer align with their needs, users can switch Mastodon servers without losing their social connections thanks to federation.
  • The decentralized nature also makes the platform more resilient to outages. If one server goes down, the rest of the network remains unaffected.

Mastodon for business

Mastodon offers unique advantages for businesses aiming to grow brand awareness, build a community, or provide customer support. Like other social media platforms, businesses can engage with their audience and share updates. However, as a decentralized social network, it might be a better fit for some businesses than others.

For example, Mozilla launched its own Mastodon server, mozilla.social, to share updates, engage with its community, and promote its values of transparency, privacy, and open-source development.

If your brand focuses on privacy, open-source technology, or decentralization, your presence on Mastodon, like Mozilla’s, can demonstrate your commitment to these values. You’ll be able to foster trust and loyalty among your existing audience and attract more people who value these principles.

On Mastodon, businesses can also provide customer support, gather feedback, and address concerns. The ad-free, real-time feed is great for answering customer inquiries quickly, which is especially useful in crisis situations.

Businesses can also customize the look and feel of their brand using Mastodon’s branding toolkit to incorporate the available Mastodon logos, icons, and brand colors to match their own.

Mastodon is open-source, so with appropriate technical skills, the entire interface can be customized. You can also use ready-to-use user interfaces, like Bird UI.

When setting up a business profile, it’s important to select a server that aligns with the brand’s values and target audience. For instance, if you’re running a PHP-based software house, join phpc.social for discussions on the PHP programming language, frameworks, packages, tools, and more.

Then, customize your business profile with display names, logos, or other branded materials in the avatar or the header. Create a concise and engaging bio that reflects the brand’s mission, with links and hashtags relevant to your brand.

On top of that, Mastodon’s customizable metadata is a quick way to add extra information that is easy to scan and helps recognize what the brand is about.

Mastodon offers no ad campaigns to increase a profile’s reach. For businesses on Mastodon, the only way to grow a presence is to organically participate in discussions and share valuable content.

Pro Tip

People on Mastodon appreciate moving away from algorithm-driven feeds and targeted ad campaigns. Get your community interested in your brand by sharing content that is informative, entertaining, or relevant to your audience, like industry insights or tips.
