Building social media is a human problem, before it is a technological one. A decentralized architecture introduces new problems without solving old ones.
Bluesky and the AT Protocol: Usable Decentralized Social Media
Bluesky is a new social network built upon the AT Protocol, a decentralized foundation for public social media. It was launched in private beta in February 2023, and has grown to over 10 million registered users by October 2024. In this paper we introduce the architecture of Bluesky and the AT Protocol, and explain how the technical design of Bluesky is informed by our goals: to enable decentralization by having multiple interoperable providers for every part of the system; to make it easy for users to switch providers; to give users agency over the content they see; and to provide a simple user experience that does not burden users with complexity arising from the system's decentralized nature. The system's openness allows anybody to contribute to content moderation and community management, and we invite the research community to use Bluesky as a dataset and testing ground for new approaches in social media moderation.

When Jack Dorsey, founder of the very centralized social media platform, Twitter, posted this message about decentralized social media, our DWeb community took note:

FediForum | Growing the Open Social Web:<br>An Online Un-Workshop
Since the Twitter takeover by Elon Musk over three years ago, the Open Social Web has been adopted by an enthusiastic community. People world-wide are building and using open social platforms and open social protocols to better interact with others online.

Seeing the Politics of Decentralized Social Media Protocols
Calls to decentralize feed-based social media have been driven by concerns about the concentrated power of centralized platforms and their societal impact. In response, numerous decentralized social media protocols have emerged, each interpreting “decentralization” in a different way. We analyze four such protocols (ActivityPub, AT Protocol, Nostr, and Farcaster) drawing on protocol documentation, media coverage, direct usage, and semi-structured interviews with protocol developers and experts to situate each protocol within its socio-technical goals. To support this analysis, we develop a grounded lexicon that facilitates the description and comparison of analogous components across each protocol. With it, we show how each protocol distributes control over key components differently, shaping who holds power over critical aspects such as user identity, curation, and infrastructural ownership. By examining protocols as socio-technical artifacts, we show how they prioritize different values and make distinct trade-offs, providing CSCW researchers with a lens to more effectively evaluate and design future decentralized social media systems.

"It falls to both the tech companies that built these systems and an engaged public to create technologies designed for social cohesion."

One of the issues that has come up again and again in my reporting on misinformation and social media is the massive influence social media companies have on research in the field. Last night a preprint dropped that tries to get at this with some numbers. My piece in @science.org (and 🧪🧵 coming):
