Trying to figure this out as in the recent threads a few people said that Bluesky was federated, but it didn't seem to actually be the case.
https://bsky.social/about/blog/02-22-2024-open-social-web in February announced that Bluesky would allow federated servers
The Bluesky documentation on the topic isn't very clear. They mention Bluesky.social a lot, as if it's supposed to be the one central server other PDS need to federate with:
Bluesky runs many PDSs. Each PDS runs as a completely separate service in the network with its own identity. They federate with the rest of the network in the exact same manner that a non-Bluesky PDS would. These PDSs have hostnames such as morel.us-east.host.bsky.network.
However, the user-facing concept for Bluesky's "PDS Service" is simply bsky.social. This is reflected in the provided subdomain that users on a Bluesky PDS have access to (i.e. their default handle suffix), as well as the hostname that they may provide at login in order to route their login request to the correct service. A user should not be expected to understand or remember the specific host that their account is on.
To enable this, we introduced a PDS Entryway service. This service is used to orchestrate account management across Bluesky PDSs and to provide an interface for interacting with bsky.social accounts.

Self-hosting a Bluesky PDS means running your own Personal Data Server that is capable of federating with the wider Bluesky social network.

The custom domain name is still something else, and does not seem to require a PDS: https://bsky.social/about/blog/4-28-2023-domain-handle-tutorial
So, to come back to the title question, do people know of an example of PDS that can be used to access Bluesky without being on the main server?
Why would someone host a server and pay for it out of their own pocket, when the protocol just turns in to an invisible piece of infrastructure that people don't even know exists?
AP instances allow for communities and identity to build around them, so there is a non monetary incentive to running them, but what's the incentive to run an equivalent on bluesky and make it public?
Definitely, that's why I guess there are still no other server than Bluesky's
@Blaze @ada @fediverse There is a small number of personal PDSes, plus Bridgy's one: https://blue.mackuba.eu/directory/pdses, but right now there aren't really any public open-signup ones, because they're limiting them to 10 users per PDS in this phase (I mean you can create more, but they won't be seen by the Bluesky relay). They implied that the network/software is not yet ready for this yet at this point, because a lot of things are still in flux (e.g. they're adding OAuth now).
