Let’s say:
- I am on instance A.
- I browse on a community that is on instance B
- a user from instance C post something on that community B.
Now i want to share a link to this post. Which instance should i pick?
- A my home instance
- B the community
- C the post author
Theoretically, it shouldn’t matter.
In the ideal case every connected server should host a full and complete copy of the data from the originating server (as xkdrxodrixkr@feddit.org says, that’s B)
Reality is a bit different, but not enough to warrant always picking B. Just share whichever you’d like, but B is the most right.
