Broadcast social media is so odd to me now. It feels like walking to the center of town and shouting about your life to everyone.
I go to Facebook once a week or so, scroll for about a minute, then close it. It was a novel experience reconnecting with people from my past, but in the end, I just found out too much about people, realized it may be best to let people in your past stay there, and that comparison is truly the thief of joy.
Now, I just like watching interesting people talk about interesting things. I get that here, somewhat, reddit but lately only in a very narrow way, tik tok as long as I carefully maintain the algorithm, and youtube. All of them I have to be careful with, otherwise I can get pulled into hellholes of outrage bait. And I'm really, really wary of engaging in dicussions anymore. HN is about the only place, and even then I often regret it.
One time, on reddit, there was a discussion about dishwashers, and how people needed to clean food off dishes, otherwise it would fill up the filters. I posted a link to a user manual showing that it was common to hook up the dishwasher to the garbage disposal to take care of that. I was downvoted into deep negatives, and I think one or more negative replies for just posting something simple and factual.
Even here, half the time I post, I feel I will end up regretting it.
I've had the same mental model as you (shouting in a town square) and that's why Twitter always seemed weird to me.
Lately, I've found that another mental model fits that sort of medium even better:
Hot takes scrawled on the bathroom walls of pubs.
