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”

Hard decentralization refers to the emergence of a resilient and multi-stakeholder Atmosphere that relies less on Bluesky PBC's existence. There's some overlap with the other two goals here. Improving things like sync make it easier to run alternate infrastructure like Relays and Appviews, and our governance work should help build confidence that the protocol is a genuine public good that's larger than Bluesky.
To support the goal of hard decentralization, we're also tackling some specific technical challenges.
Improving Non-Bluesky PDS Hosting
The decentralization guarantees of AT come from the locked-open substrate of data hosted by Personal Data Servers (PDSes). One of our current goals to increase the resilience of the network is to encourage more non-
Bluesky PDS hosting.

Before we dive into what we're up to, let's take a moment to celebrate what's happening in the Atmosphere. Our little network is really starting to hit its stride. The energy is incredible and growing by the day!
We're seeing new projects pop up constantly, and there's a new level of maturity across the board.
