@smallcircles🫧 socialcoding.. your question is a cognitive dissonance for me.

Firstly, I've only ever experienced Google+ circles in an environment where the participants are similar to LinkedIn, posting about professional topics and/or corporate syncophacy. They are a good way to seal yourself into an echo chamber/bubble, even within that type of discourse

Secondly, influencer social media always feels more like people pitching their point of view or hot take or maybe just themselves. It's about collecting follower count for credibility. Fedi mostly isn't like that but there are some.

Lastly, I'm in the US, right now with political situation there is necessarily disruption and shouting and points to be made. (Some of them might even be correct!). But it does affect social media experience; it would probably make matters worse to increase the echo chamber effects.
