Hey; the feddit.uk one got deleted as the owner purged his account :/
From what I can tell, this one is currently the most active community and has most subscribers, but I'd think it might make sense to subscribe to both to just also get the content if posted there :)
Huh, you're right it looks like they've deleted the feddit.uk one. I wonder why!
The Kbin one is definitely not empty but you might just be the first subscriber from your instance and it's not great at pulling in old posts. New ones will show up though. Not that there's a whole lot going on there either atm in July!
I just subscribed, hope to see something there soon. On my search for Eurovision I saw plenty of communities but most showed only one user, but maybe being at Lemmy.world limits the number of users I see in communities elsewhere? Hmm I guess I'll subscribe them all then 😅
