The Promise of an Open Feed
For years, users have complained about social media giants controlling their online experience. Algorithmic feeds, designed to maximize engagement, can create filter bubbles, promote outrage, and turn user data into a commodity. In response, a new wave
of 'open' or 'decentralized' social networks has gained traction. Platforms like Mastodon and Bluesky are built on protocols that don't belong to a single company. Their primary appeal is often a simple, chronological feed of posts from accounts you choose to follow. This promises a return to a more authentic, user-controlled social experience, free from the mysterious whims of 'The Algorithm'. The idea is to give power back to the user, allowing them to own their online identity and curate their own space.
The Moderation Nightmare
The biggest challenge for any social network at scale is content moderation. In a centralized system like Facebook or X, a single company sets and enforces the rules. In open networks, this becomes incredibly complex. Mastodon, for example, is a 'federation' of thousands of independent servers ('instances'), each with its own administrator and rules. This means moderation is inconsistent by design. While this allows for niche communities with specific norms, it also makes it difficult to tackle widespread issues like harassment, hate speech, and disinformation. If a user is banned from one instance, they can often just move to another. This distributed nature makes it challenging to enforce a baseline level of safety across the entire network, leaving individual server admins—often volunteers—to manually screen and remove harmful content.
The Discovery and Discovery Dilemma
As much as we criticize them, algorithms are exceptionally good at one thing: helping us discover new content and creators. They connect us to trending topics, interesting conversations, and accounts we might like. In a purely chronological, algorithm-free world, this 'discovery' function is largely absent. Your feed only contains posts from people you already follow. This can make the experience feel quiet, small, or even boring. Without a central mechanism to surface relevant content, finding new communities or joining a global conversation becomes a manual and often difficult process. Users must rely on hashtags, personal recommendations, or third-party tools, which adds a layer of friction that mainstream users may not tolerate.
Safety Tools in a Decentralized World
Beyond broad moderation rules, effective safety relies on robust tools for users. On traditional platforms, you can block, mute, and report users with the expectation that a central safety team will review the case. On open networks, these tools can have limited reach. Blocking a user on your Mastodon instance might not prevent them from seeing your public posts from another instance. Studies have found that many decentralized platforms lack the essential technical tools for managing harmful content at scale, such as systems to automatically detect and remove spam or phishing links. This puts a much heavier burden on the individual user to curate their own safety, which can be exhausting and, for many, a deal-breaker.
Building a Better Toolbox
The good news is that these platforms are aware of their limitations and are actively trying to solve them. Bluesky, for example, is pioneering a 'stackable' approach to moderation. It provides a baseline of safety but also allows users to subscribe to third-party moderation services and custom-built filtering lists. This means a user could subscribe to a filter that hides all posts containing spiders, or a list maintained by a trusted community group that flags misinformation. Similarly, Bluesky's ecosystem of custom feeds allows users to opt-in to algorithmic discovery on their own terms, choosing from countless feeds created by the community. These innovations are an attempt to find a middle ground: offering the tools for safety and discovery without forcing a single, centralized vision on everyone.
