@ColonelThirtyTwo Sorta/mostly. The protocol has a bit of a different model then Activity Pub, and it’s in development so there are some limitations, but it’s been opened and there’s people hosting their own PDSs now (the part of Bluesky that hosts your account).
To my knowledge there’s only two AT relays (the part that aggregates content from PDSs), Bluesky itself and very recently frontpage (a link aggregator). That makes the network fairly centralized right now, although BlueSky/AT has made a lot of progress in the last 9 months in terms of opening up so I expect it’ll be a lot less centralized this time next year. I’m also betting that somebody will make an AT client that pulls posts directly from PDSs instead of going through a relay at some point.
@5teverin0 @SharkAttak The lines kinda blur in some places, but mostly just no max post length, text formatting, and a layout that more resembles a blog as apposed to a twitter profile (tags/categories, about page, that sort of stuff). You also usually get a domain or sub domain (example.com or user.example.com respectively) instead of just a handle (e.g. example.com/@user) so that it’s easier to use as an independent website.
