About me & this article

Over decades of experience as an IT consultant, I have accompanied many projects. One pattern keeps recurring: good technical decisions are only made when the pressure to act is great and management has been clearly informed. In the digital age, this pressure remains consistently high and is also acute. The ubiquitous dependencies on external service providers in other countries and under other legal systems are particularly difficult.

A second pattern is equally reliable: the decisions that later cause the greatest costs appear unspectacular at the moment they are made. The choice of a communication platform is one of them. It is a central strategic question.

I want to help management and decision-makers ask this question early enough. Not with too many technical details. But with the criteria that matter for executive boards, supervisory boards, managing directors, and the governing bodies of public institutions: risk, cost, control, independence, impact.

This article is not a plea for a specific product. It is an assessment framework. It is intended to make visible the questions that should be answered before a decision is made. And it is intended to show which answers the Fediverse already provides today. In this way, it serves as a counter-model to the tempting offers of centralized tech corporations. These offers appear attractive because they are convenient, because they promise reach, and because they are quickly available. The price for this often only becomes apparent later: dependency, data loss, rule-setting by third parties, and rising costs. The assessment framework is intended to make these connections visible before a decision is made.

The Fediverse is not one of the old classic platforms. It is the most modern and most resilient infrastructure.

With a single account! On the platform of your choice! With the provider of your choice! From a server in the country of your choice!

That is the idea of the Fediverse!

The principle of the Fediverse is similar to the email system: Anyone who has an account with one provider can send messages to people with other providers. The Fediverse works in the same way. One account on a Fediverse instance is enough to see and interact with posts from people on Mastodon, Friendica, Pixelfed, PeerTube, and on all platforms throughout the entire Fediverse.

The Fediverse is a federated association of independent social networks. The name is composed of the English words “federation” and “universe.” The idea behind it: instead of one central corporation, many different companies, organizations, or private individuals operate their own servers. These servers exchange with one another using a standardized ActivityPub protocol and together form one large whole.

This is what we mean when we talk about platforms in the Fediverse, such as Mastodon or Friendica, etc.

Full control - independence from networks

Centralized platforms such as X, Instagram, or YouTube each belong to a single company. It can change rules at any time, adjust algorithms, or even shut down the platform. In the Fediverse, the network belongs to no one alone. It consists of independently operated servers (instances) that are connected to one another via the open ActivityPub protocol. The number is open-ended. If one instance fails, the others simply continue running. The French research consortium CNRS emphasizes precisely this point: the decentralized architecture protects against central outages, arbitrary closures, and takeovers by individual actors.

Examples in Germany: German Society for Higher Education Didactics e.V., Society for Media in Science, DIPF Leibniz Institute for Research and Information in Education, Political Science Information Service, Research Data Infrastructure (NFDI), Forschungszentrum Jülich, Society for Scientific Data Processing mbH Göttingen (GWDG), Hasso Plattner Institute, Helmholtz Association, Information Service for Science, Karlsruhe Institute of Technology, Berlin State Library, Zentral- und Landesbibliothek Berlin, Digital Humanities in the German-Speaking Region (Dhd Association), Worms University of Applied Sciences, Furtwangen University, Federal Commissioner for Data Protection and Freedom of Information (BfDI), City of Krefeld, Norddeutscher Rundfunk (NDR), Heise Medien, ARD, ZDF, SWR, and many other commercial and private operators.

Information can be distributed publicly or exclusively. Received with or without an account. No longer must information be shared in areas sealed off from the public, search engines, or AI searches, such as email newsletters, WhatsApp, Telegram, and other networks. Offers and advertising can be distributed to all channels at once. Or offered exclusively to subscribers with a single click.

Future-proof - sovereignty from tech corporations

A single provider can discontinue its service, close its API, change its rules, or alter its business model. Every operator who bases their communication on a centralized platform carries this risk. In the Fediverse, the presence is distributed across independent instances. The failure of one instance affects only that one instance. Reach is preserved because the federation continues to run. Risk minimization with clever technology.

Anyone present on a centralized platform today is renting space. The landlord sets the rules. In the Fediverse, a company or organization can set its own rules, establish its own priorities, and build its own communities. That is a difference in external impact. An organization that operates its own instance signals independence and a will to shape things. That is a hallmark that cannot be bought. For public broadcasting institutions, it is a contribution to media diversity. For companies, it is a contribution to brand positioning. For NGOs and other organizations, it is a contribution to credibility.

Data protection, data sovereignty, digital sovereignty

On commercial platforms, user profiles emerge that the operator exploits. In the Fediverse, everyone operates their own instance. Data sovereignty remains on that instance. This is an important foundation for compliance. The GDPR requires accountability for data flows. Anyone who operates their own instance can provide this accountability without gaps. For companies, public broadcasting institutions, and NGOs with sensitive target groups, this is an operational advantage.

Traditional content distribution has a structural weak point: the target audience belongs to the platform operator, not to the actor. If WhatsApp changes its group function, if Telegram is restricted due to regulatory requirements, if an email delivery rate suddenly collapses - the actor can only watch. The Fediverse offers a fundamentally different architecture here.

An own instance can serve as a point of contact for interested parties, where they receive the information they want. This means interested parties subscribe to the news directly at the source. No administration of accounts and personal data. GDPR compliant by design. No subscribe/unsubscribe mechanisms. Even with regulations for the protection of children and young people: no problem, since there are no accounts.

Cost sovereignty instead of cost risk

On centralized platforms, the costs for reach rise continuously. Anyone who wants to remain visible pays. The costs are limited to operating the instance. These costs are calculable, scalable, and independent of the pricing mechanisms of a monopolist. For small companies, this means: reach does not have to be bought but can simply be built up. For large companies, it means: dependence on advertising budgets is eliminated. And for both, the following applies: very good customer loyalty.

Target audience relationships belong to the operator, not the platform

Fediverse accounts are transferable. When an organization moves from one instance to another, followers automatically come along. The subscriber list built up via email newsletter can likewise be transferred to a new server. An algorithm update cannot make it disappear, a platform rule change cannot block it, an increase in advertising prices cannot make it more expensive. During its six-month test phase on Mastodon, the BBC gathered around 60,000 followers and found that the interaction rate for some posts was significantly higher than on X/Twitter - despite the much smaller user base in comparison.

Cross-service networking - federation

One account is enough for many services. Anyone registered on a Mastodon instance can follow and interact with others on Friendica, Pixelfed (photos), or PeerTube (videos) without any further account. A concrete example: a PeerTube video can appear directly in a Mastodon feed. Users can watch, like, and comment on it there without switching platforms.

Maximizing reach quality

Reach quality refers to clicks, relevance, impact, and interaction. A qualitatively more meaningful measure of reach - not just the meaningless click rate.

This solves the biggest problem of content distribution: reach is no longer limited to users within the platform. An instance operator can deliver content simultaneously to Fediverse users, email subscribers, and other recipients. Users who do not want to use commercial newsletter services for data protection reasons can subscribe anonymously here.

The numbers of interested parties in the Fediverse often look smaller than on commercial platforms. That is well known. But what is less often considered is how high the target efficiency looks in contrast to the old technology platforms. There, one must trust the operator to deliver information to the target group. One must trust that the information or advertising is actually delivered to the correspondingly purchased quantity. That information is prepared according to the operator’s specifications - the algorithm. And even more variables in which one must trust external companies that have not exactly advertised themselves as trustworthy in the past.

Maximum control & power - One2Many (O2M)

With this modern One2Many (O2M) architecture, distribution channels for interested target groups can be built very easily. Away with the outdated and limited email distributors, WhatsApp groups, and Telegram channels.

O2M - One channel for many platforms

Thanks to the ActivityPub protocol, a Mastodon or Friendica account can deliver content simultaneously to users on Pixelfed (images), PeerTube (videos), and Lemmy (forums). This means: a single post about a campaign reaches interested parties on different platforms at the same time, without having to publish separately on each platform. For small and medium-sized enterprises, this means: marketing effort is reduced from multiple manual distributions to one-time publication and automatic synchronization.

O2M - Integrated email distributor

Tastes differ and old habits are often stubborn. And here too, some projects support exactly that. An account in the Fediverse is not required. Recipients only need an email address to receive content. No Fediverse account has to be registered, no instance selected, and no technical hurdles overcome.

O2M - WhatsApp groups and Telegram channels

Again. Whether public, exclusive, with or without an account, whether notification is desired: the Fediverse offers all of this with its O2M architecture on one platform. No phone number required, no member limit, no technical or regulatory dependency on service operators. The content is synchronized throughout the entire Fediverse via the ActivityPub protocol and is therefore reachable.

O2M - Old but mighty - RSS feeds

Anyone who wants to increase profit gives away a lot of money, right? Wrong! But many companies and organizations seem to believe this principle and reduce their reach by deactivating the RSS feeds of their websites and channels. And in return, they offer interested parties hurdles in the form of closed platforms such as Instagram, YouTube, or TikTok, which interested parties must join. But the trend is increasingly moving away from these platforms. The increasingly popular term digital detox makes this very clear. The question is: is it worth continuing to operate a service that offers additional value while requiring no maintenance effort and no costs? The answer can only be YES.

O2M - Podcasts and videos

A conversation clarifies many things more quickly, and a picture says more than a thousand words. E-learning with video and audio. Podcasts and videos secure focused attention and higher interaction rates for companies today than text-only formats. With several projects, the Fediverse offers a platform for this that enables data sovereignty and direct target group loyalty without an algorithm. And of course, the same advantages over the old large platforms apply here as well. Data sovereignty and control.

Management conclusion

  1. Content distribution and customer loyalty are not cost items but the building of one’s own assets. The O2M architecture of the Fediverse makes these assets transferable, combinable, and controllable for the first time.

  2. An instance can simultaneously serve as a content distribution center, email replacement, and one-way information channel. Users can follow via email, interact via Fediverse accounts, and be reached in different ecosystems at the same time.

  3. The entire system runs on the organization’s own infrastructure - no intermediaries, calculable costs, full control of one’s own platform, clear and simple GDPR implementation, and digital sovereignty.
