or what I see are kbin users subscribed to technology on beehaw while you quote directly beehaw users?
I think so, yes (though still learning). From my point of view (lemmy.click, just 83 users):
- https://lemmy.click/c/technology@lemmy.ml - 19 subscribers
- https://lemmy.click/c/technology@beehaw.org - 17 subscribers
- https://lemmy.click/c/technology@slrpnk.net - 1 subscriber
I think this shows the number of lemmy.click accounts subscribed to these remote communities.
But when I open the communities in their home instances, I get a different picture:
- https://lemmy.ml/c/technology@lemmy.ml - 15.5k subscribers
- https://beehaw.org/c/technology@beehaw.org - 19.1k subscribers
- https://slrpnk.net/c/technology@slrpnk.net - 370 subscribers
The person you were talking to started the conversation with a screenshot showing 5 subreddits for "Blue Protocol", apparently a MMORPG. Similar examples exist for almost any subject big enough.
The phenomenon exists for all systems where there is no central authority deciding names and categories, which is true for both reddit and lemmy. Individual users can decide to create a new group regardless of existing groups, for a variety of reasons. This naturally leads to some duplicates.
