Can this be made, so the subcategory is more prominently shown in topics or lists of topics? The Austrian community subcategory is inundated by posts from German community members.
As much as community.openstreetmap.org is about countering silo-ification, there is not much won by silo-consolidation, i.e. one community being absorbed by a ten times bigger and hundred times more talkative one.
Country-specific differences can also exist in the way you interact with each other, or the words you use - not just hard-and-fast tagging rules. I can understand that even if a thing is factually the same in Austria and Germany, the Austrian community would occasionally like to form an opinion among themselves, without being “nudged” by the 100-times-more-talkative giant next door
One option is setting the Germany category to Muted. I recently did some testing of how muting categories works:
It means the posts won’t show up in the main Latest section at the root of the site, but you can still browse the category separately and you’ll still get notifications if somone mentions you or replies to a post you made in the category.
