So I know about /c/community@example.host for communities and /u/user@example.host for users, but how do I link to individual posts in a way that won’t be a hassle for people in other instances?
As I understand it, the fediverse icon links to the home instance for the community the post was made on. I don’t think there’s currently a mechanism to link a post in a way that consistently resolves to the user’s home server’s version so they can vote and be logged in while viewing it.
