@dansup I've seen conceptual talk of combined ActivityPub servers and AT PDSes. For decentralization, that certainly makes more sense than routing everything through a single bridge. The idea seems worth exploring.

It does have lots of caveats though: posts published to Bluesky cannot be edited and are always fully public, the data model (e.g. 300 chars max) is strict, and there may still be restrictions on the number of accounts per PDS. So check your assumptions carefully.
