The likely answer to this is that there will always have to be a large corporation at the heart of Bluesky/ATProto, and the network will have to rely on that corporation to do the work of abuse mitigation, particularly in terms of illegal content and spam. This may be a good enough solution for Bluesky’s purposes, but on the economics alone it’s going to be a centralized system that relies on trusting centralized authorities.
Just a note, a lot has changed since then: https://app.wafrn.net/fediverse/post/34675fdb-40fa-4696-8a3c-40126d428681
Any link to a non-Bluesky instance where people can register? I couldn't find it in the thread
There is no generic one available right now, though its easy to self host. iirc, there's ~1000 PDSes right now, which is pretty small compared to the fediverses 17,000.
Wafrn (app.wafrn.net), technically counts as they have bluesky integration.
If it's easy to self host, why is there none publicly available?
Because there's little incentive.
Anyway, wafrn does count, in my opinion.
There's as little incentive to host a Lemmy instance.
I am having a look at wafrn, do you have an example of a Bluesky account visible from there? I only see local accounts.
