What’s the mechanism of resolving a user ID in Nostr? It seems that a user identifier will resolve to readable username on content detail view.

Any spec on how to resolve the identifier when seen on the feed?

If Bluesky uses different protocol, will it implement Nostr protocol later on? Just wondering on how to federate messages across these different apps / protocol clients.

probably some margin and alignment with the text instead of full bleed. otoh, the scrolling when loading a post thread is much smoother now, much better experience on smaller screen.
