When our instance goes down or gets sluggish or something isn't working, people can just like... Put a message in our chat of a few dozen people. And then one of us can go look at the server and see what's going on and fix it. The worst case scenario is that our members temporarily lose access, but everyone else on fedi is fine. I'm happy to do the work, I have learned a lot from doing it, and I really enjoy keeping the lights on so our lovely members have an independent means of reaching the world.
when bluesky goes down, there's nobody to contact, and its just down for some unknowable subset of everybody. My account is on Blacksky (and org I think is rad as hell and doing it right), so I try to go access directly from Blacksky. That sort of works, I can see things, but now interactions from bluesky-hosted accounts are buggy, coming in and out of existence. I don't think the bug comes from Blacksky, its from bluesky, but I can't really know, and there's nobody to tell.
This is really the thing that keeps me from being more involved and interested in atproto - the feeling of just being along for the ride. For all its faults, the thing activitypub does is situate you within a group of people you get to know and are responsible for each other. There is some way this could be done with atproto, but I haven't seen it done yet. I don't mean it has to be fully vertically integrated so one group runs everything for its members, though that is a highly legible organization, just that the pieces are known, knowable, run by people you know, and you have some material stake and say in how they work. I like what I'm seeing from Blacksky in that direction, and maybe in a few years we'll see hundreds of independently run and moderated communities. We have that here, now, for all fedis faults, and until I see it elsewhere that's the thing that keeps me here.
