Yes, for browsing and up/downvoting it could be totally transparent. When you want to make your own thread it could just have you select the specific magazine/commumity from a drop down.
edit: even commenting on existing threads would be totally seamless.
The others have been answered, so here are 3 and 4 to my understanding:
Click the + at the top right and you can make a new thread to the current magazine (subreddit) or even make a new one.
Microblog for each magazine pulls in all mastadon and other fediverse content that has the tags that the magazine owner has associated with it.
I’ve mentioned this elsewhere but it could just be a UI thing handled by/for each user, that way moderation and control will stay where they are
Basically I could make a group of communities/magazines, for example
selfhosted@kbin.social
selfhost@lemmy.ml
selfhosted@lemmy.world
selfhosting@chirp.social
selfhosted@lemmy.ml
selfhosting@slrpnk.net
For browsing, up/downvoting, and commenting it could be totally transparent. When you want to make your own thread it could just have you select the specific magazine/community from a drop down.
This wouldn’t fix the problem of seeing multiple duplicate posts from each.
