An extra annoying problem about social media for me is that while I can make most of the platforms give me a chronological feed of content authored only by people I follow, most other people see mine in an algorithmic feed. This includes people I have zero social connections with. For example, I just gave up trying to discuss politics on Twitter, because every time I post anything political, that tweet ends up in the feeds if hundreds of people who hold the radical version of opposite views, with predictable results. And there's nothing I can do. I can't opt out of being recommended.
