Twitter's algorithm promotes whatever tweet will make people angry, because angry people spend more time on Twitter. I'm on Twitter, but I've been on Twitter for a while now, I've selected who I follow, and my feed just doesn't get that kind of noise in it at any significant level. Most of what I see on Twitter is people arguing about Elden Ring or showing off how they can access YouTube from a Mac SE or something.

"The news" is dominated by organizations which are trying to maximize their social media engagement metrics so they can get more money from advertisers, so they're subject to the same forces that drive Twitter.

Neither of these sources reliably give you a picture of national affairs. Right now the best I can do is get a picture of local affairs by talking with people that I happen to encounter because I live near them.
