I have an account on lemmy.ml, as you can all see.
My partner has an account on lemmy.world
When I link a post, let's say this one I picked at random, it is a link to a specific post ID on lemmy.ml
If I send this to my partner, as I do with a lot of things we both enjoy, they will be able to read it, but not reply/respond, as they don't have a lemmy.ml account. The post ID for the same post is different via lemmy.world, obviously.
This post even originated on lemmy.world, sort of, as it's poster is from there.
We send each other links like this all the time, and on reddit or hacker news, that's not a problem. There can be only one HN, after all. Lemmy is not so monolithic, and it looks like this is a serious downside.
I can't reply to other instances than my "home instance", and I can't easily discover what the post ID for this post is on my home instance, so my interaction/"engagement" is probably going to be very low for things I didn't discover myself.
Am I missing some functionality here?
