Maybe I misunderstand. The screencap is a video. It shows a near infinite amount of loading of lots of different things from lots of different places, but it also looks like it might be stuck in an infinite loop bug and if so I guess I retract my "BlueSky is dead" comment. If not, if it actually has to load all that crap, then that is not gonna fly.

Yes, looked like an infinite loop. The official client is much better. Just use the official client, do not trust unofficial clients. Bluesky is open, interoperable, fast, works great, as long as you use the official client and server.
