Fediverse Sharing: Cross-Platform Interaction Dynamics between Threads and Mastodon Users

Traditional social media platforms, once envisioned as digital town squares, now face growing criticism over corporate control, content moderation, and privacy concerns. Events such as Twitter's acquisition (now X) and major policy changes have pushed users toward alternative platforms like Mastodon and Threads. However, this diversification has led to user dispersion and fragmented discussions across the walled gardens of social media platforms. To address these issues, federation protocols like ActivityPub have been adopted, with Mastodon leading efforts to build decentralized yet interconnected networks. In March 2024, Threads joined this federation by introducing its Fediverse Sharing service, which enables interactions such as posts, replies, and likes between Threads and Mastodon users as if on a unified platform. Building on this development, we study the interactions between 20,000+ Threads users and 20,000+ Mastodon users over a ten-month period. Our work lays the foundation for research on cross-platform interactions and federation-driven platform integration.

Navigating Decentralized Online Social Networks: An Overview of Technical and Societal Challenges in Architectural Choices

Decentralized online social networks have evolved from experimental stages to operating at unprecedented scale, with broader adoption and more active use than ever before. Platforms like Mastodon, Bluesky, Hive, and Nostr have seen notable growth, particularly following the wave of user migration after Twitter's acquisition in October 2022. As new platforms build upon earlier decentralization architectures and explore novel configurations, it becomes increasingly important to understand how these foundations shape both the direction and limitations of decentralization. Prior literature primarily focuses on specific architectures, resulting in fragmented views that overlook how different social networks encounter similar challenges and complement one another. This paper fills that gap by presenting a comprehensive view of the current decentralized online social network landscape. We examine four major architectures: federated, peer-to-peer, blockchain, and hybrid, tracing their evolution and evaluating how they support core social networking functions. By linking these architectural aspects to real-world cases, our work provides a foundation for understanding the societal implications of decentralized social platforms.

How do Mastodon and Threads actually interact?

Our latest paper on Fediverse sharing is out! We look at how these platforms connect, the impact of integration, and how users perceive it. Some Mastodon servers welcome Threads, while others block itโ€”shaping the relationship between decentralized and centralized social media.

What does this mean for the future of social media? Read our findings here: https://arxiv.org/abs/2502.17926

@heliomass I tried to contact you through BlueSky. could you reply back to me when you have a chance? I am researcher studying social media and would like to hear more details about your tools

Here's #Bluesky spiking in the UK following Elon Musk's trash talking Britain. Anyone know if #Mastodon or other parts of the #Fediverse saw a spike?

Don't forget to follow @bsky.brid.gy to bridge to Bluesky so people can follow you. Ask them to follow @ap.brid.gy on Bluesky so you can follow them back.

Bridgy Fed is one of the efforts aimed at connecting the fediverse with the web, Bluesky and, perhaps later, other networks like Nostr.
