Two very interesting things I noticed about this post by #Bluesky (which I discovered via @solimaniac_).

☝🏾 Bluesky is differentiating themselves from the #Fediverse (which is primarily built on #ActivityPub) by referring to what they are creating as the #Atmosphere

✌🏾 Bluesky admits what they have built thus far is not truly decentralized as they want to embrace “hard decentralization”

It should be stated the purpose behind this analysis was not to dump on #Bluesky, but rather to create a framework for assessing progress of these networks to stated goals of decentralization. Note the #ATmosphere, while very centralized, is making progress. The trend line is positive, mostly due to users moving to #Blacksky.

The usefulness of this analytic is that instead of just accepting marketing statements we have a quantifiable basis using accepted statistical models to refer to.

Astronomers found an #atmosphere where they least expected it—clinging to an #exoplanet that’s too small, too hot and too old to have air, at least in theory.

Observations of the blazing-hot lava #planet TOI-561 b suggest not only that it has a thick atmosphere but also that it may have had one for billions of years.

This is the strongest evidence yet for "air" around a hot rocky world that isn’t just a temporary veil of #hydrogen and #helium left over from planetary formation.

But even if all of #threads would be part of the #fediverse and make the fediverse practically centralized, it wouldn't change the the factual situation that
a) #mastodon is #decentralized,
b) #bluesky as being controlled by a single company is completely centralized, and
c) #atmosphere as being dominated by #bluesky is practically centralized.

No, I'm not saying that #atmosphere is controlled by a single company.

I'm just pointing out that right now #atmosphere is centralized in practice in the sense that it consists basically exclusively of infrastructure controlled by #bluesky PBC.

Do I understand you currectly that you are comparing #bluesky to #meta?

Nonsense.

Of course, when considering #threads as a part of the #fediverse, then it's not #decentralized.

But this does not change the fact that #mastodon is #decentralized. As is the #fediverse excluding #threads. As show nicely by the diagram.

And of course all this does not change the fact that #bluesky is controlled by a single company. And that #atmosphere is centralized. As also shown nicely with the diagram.

I know people are arguing in the comments of this post, but —

Can we notice that — there is a conversation happening across the Fediverse, ATmosphere, Mastodon, and Bluesky.

And, consider that some level of success for the broader Social Web 🙂

Just finished listening to @boris's @fedicon talk about the #Atmosphere for fediverse people, and I listened to it "as a podcast" through @AntennaPod via RSS via @peertube. Protocols on protocols!

Interesting to look back at this five months later ... here's what's currently happening today in terms of decentralization the ATmosphere.

• @rudyfraser.com announced today that Blacksy feeds and moderation service are now powered by our own atproto relay -- and it's an independent implementation, not using Bluesky's reference code. It's really worth reading the thread, which has a great analogy for how a relay enables custom feeds.

@edavis.dev has configured deer.social (a third-party app) to to point to a self-hosted bsky appview which reads from a self-hosted relay which subscribes to a self-hosted PDS which is where this -- as he says, "Bluesky independent from Bluesky".

• @bnewbold published A Full-Network Relay for $34 a Month, updating his post from last summer. The network size has increased by close to an order of magnitude since his first post; the cost of a realy

• #FreeOurFeedsis donating a $50K to the AT Community Fund to support the #IndieSky working group. The notes from last week's Ahoy IndieSky Europe give a sense of the energy here -- and also link to a bunch of other projects that sure look decentralized to me and discusses the prospects of Eurosky.

Of course, like I said in the article,

""Decentralization" means different things to different people. As the links in the Appendix highlight, people who are focusing on the (very real) concentration of power in the ATmosphere today, or the potentially-centralizing architecture of AT, find it more useful to describe Bluesky as centralized."

And the power concentration -- or "operational centralization" as Bluesky folks were calling it at the ATmosphere Conference -- is still very real. Bluesky still runs almost all of the infrastructure for the ATmosphere, and it's by far the most popular app, and most other apps (as well as Bluesky) use the Bluesky AppView, Relay, and labeler.

Then again, that's clearly in the process of changing, and it'll be interesting to see how it looks six months or a year from now.
