@zuck.bsky.app
and
@zuck.meta.com
are two different accounts.
The only “problem” bsky solves is choosing a server. But if ATProto becomes widely used, the problem will appear as in Mastodon today. The only way to avoid it is for bsky to never become really decentralised. So yet another VC-backed social media company.
I think there's no two ways around it, @stephenking.bsky.social looks better than @stephenking@mastodon.social.
Blue Sky does the names better and opts people into a default server at the moment, and I would say their desktop and mobile experience is a bit better, and that feels like they've solved something specific and technical even though, as you pointed out, the issue with domains is the same in each case.
