Recently due to various events (namely a lot of people getting off of X-Twitter), Bluesky has become a lot more popular, and excitement for its underlying protocol, ATProto, is growing. Since I worked on ActivityPub which connects together Mastodon, Sharkey, Peertube, GotoSocial, etc, etc, etc in the present-day fediverse, I often get asked whether or not I have opinions about ATProto vs ActivityPub, and the answer is that I do have opinions, but I am usually head-down focused on building what I hope to be the next generation of decentralized (social) networking tech, and so I keep to myself about such things except in private channels.
On discourse and decentralisation
Over the last year, as Bluesky got more popular, conversations about whether Bluesky and ATProto are really ‘decentralised’ have gotten more “popular” as well. These conversations ranged from high-quality, productive back-and-forth articles to people just saying a lot of dumb stuff on the internet (shocker, I know). As time went on, this discourse has grown […]

Be Wary of Bluesky
Bluesky promises decentralization, but nearly every user's data sits on Bluesky's servers, and every new ATProto app reinforces that centralization. T
Re: Re: Bluesky and Decentralization -- Dustycloud Brainstorms
A few weeks ago I wrote How decentralized is Bluesky really?, a blogpost which received far more attention than I expected on the fediverse and Bluesky both. Thankfully, the blogpost was received well generally, including by Bluesky's team. Bryan Newbold, core Bluesky engineer, wrote a thoughtful response article: Reply on Bluesky and Decentralization, which I consider worth reading.

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.

A conceptual model of ATProto and ActivityPub
If you were to design an open social networking protocol, what would that look like? Which metaphors and comparisons would you use to get a general idea of how the network functions? And what would you answer if people ask if your network is decentralised and federated?

Looking AT the Blue Skies of Bluesky
The pitfalls of centralized social networks, such as Facebook and Twitter/X, have led to concerns about control, transparency, and accountability. Decentralized social networks have emerged as a result with the goal of empowering users. These decentralized approaches come with their own trade-offs, and therefore multiple architectures exist. In this paper, we conduct the first large-scale analysis of Bluesky, a prominent decentralized microblogging platform. In contrast to alternative approaches (e.g. Mastodon), Bluesky decomposes and opens the key functions of the platform into subcomponents that can be provided by third party stakeholders. We collect a comprehensive dataset covering all the key elements of Bluesky, study user activity and assess the diversity of providers for each sub-components.

This is a really insightful thread that points out some of the fundamental issues with the Bluesky community vs Bluesky as a decentralized protocol. This thread is also why I think it's a really smart move for Bluesky to appeal to fandoms... (cont.)

One of the Atmosphere’s big bets is that the next 100m users will be won by making decentralised tech + data sovereignty more compelling. I’m less than convinced. We may be solving problems only builders care about, while overlooking problems that actually make ordinary people choose a network.
Bluesky is not a social network or a product or a service, it is fundamentally a promise - a promise that you can decide — with others in your social geography — where you want to be in the digital world, and you don’t have to lose all of the bits that represent you in the process.

Is Bluesky dying? Is it the community's fault? Should people here refrain from criticizing journalists who think J. K. Rowling might have a point? The thing is, it doesn't matter. Because the answer isn't to make Bluesky change. It's to take advantage of Bluesky's tech to build something else.
It's hard for non-technical people to understand that #atproto (Bluesky, and friends) really is a different breed of social software. One where our data, and connections are no longer taken hostage by the platform and we're free to store our data wherever we want
Many people are talking about decentralized social media protocols like #ActivityPub and #ATProto and all the amazing things one can do with them. But do you actually know how they work? We thought we'd do something about this. Come to #FediForum next week if you are curious and like to find […]
Original post on mastodon.social
mastodon.socialSome of us in the ActivityPub world feel jealous of AtProto’s success (like me). But more decentralization is a win for everyone. With Bridgy from @anew.social connecting protocols, this isn’t competition, it’s momentum. We’re stronger together, so let’s build the social web humanity deserves 🚀
