It's also the way most social networks work. If the OP posts privately, all the comments and replies to comments are visible to *all* the OP's followers.
This is how Facebook, Instagram, and X all work.
They let you have private conversations with people that matter to you. It's one of the best parts of those platforms.
@nina_kali_nina For researching things like this, it's unfortunate that no search engine lets you easily say "give me results in ALL languages, I'll figure it out, don't worry". Even DDG with the country switch off seems to filter by rough region/language based on GeoIP, at least until you reach the second page of results.
Yes. That's equivalent to Alice setting their post followers only, and Bob setting their post public, but less confusing to the user.
(Edit: realized you hadn't said what Bob's visibility was set to. Anyway: UI quibbles aside, the answer is that you intersect the people who are able to view)
@nina_kali_nina It's more just luck that my country speaks one of the 2 languages whose Wikipedia mentions this fact :) Here in Germany, putting "ubuntu morphix" into any search engine naturally shows this Wikipedia article as one of the top results, and at least DDG even highlights the relevant sentence in the text preview.
@bryan turns out: yes! I need to either print a new head/fan housing or buy an upgraded dual fan kit, or it will print hot garbage. I am doomed by Projects!
