It should be noted that Feddit.org was included to represent Germany, Austria and Switzerland.
I did not include Baraza.africa as that was too encompassing as it covers the whole African continent.
Hopefully this post inspires more countries to join the blue club!
Your list is pretty comprehensive!
You could add:
https://lemmy.world/ to 🇳🇱
Maybe https://slrpnk.net/ to 🇵🇹 as that’s where they’re hosted.
Also you can add the Lechestein flag 🇱🇮to Feddit.org as they’re German speaking.
