And that was one of the brilliant things about Google+:
You could post under different topics so people could read my programming or local posts without having to cope with my religious or political posts (just examples, I never got around to the two last ones I think).
Another thing was - after Google lost the nym wars their ux for using pseudonym accounts became one of the best I was aware of (no, it is not the same as the multiple-logged-in-accounts ux which I find rather unsatisfactory, but I guess parts of it lives on in YouTube were I can still see my pseudonym(s) when I log in.)
I don't think that would work thesedays. If you had a political post, I'd say you'd correctly keep it in its correct circle (based on you highlighting the feature here), but since Google+ was a thing, a new generation of twitter addicts have the mantra of "everything is political, even looking at a keyboard is a political act, politics affects everything you do, even if you just sit there, so that's why my political rant is in your model train collector circle #sorrynotsorry"
So they'd abuse the circles feature with that mantra as an excuse.
I want a social network where I can choose to follow people and some tags - want to be able to follow you, when you are not talking about politics and remain 100% ignorant of any posts you make about politics.
I'm not sure how Twitter works now, but I imagine that a system of bot generated topics rather than direct following would be better suited for people like me.
Hashtags don't work, anybody can put any hashtag they want, even when the tweet is completely unrelated to the hashtag.
