@inthehands I hate how well this explains so many of the interactions on here. Now I'm trying to imagine how I could unflatten timeline views to make it more clear at what level a post could have been intended for the reader.
Like, I'm more welcoming of replies from my followers than total strangers. More still from mutuals, and people I've exchanged replies in the past. That kind of thing could feed into some UI nudges to remind people of the actual social distances involved.
