Unfortunately, the devs at Twitter hate the way I use it. Nowadays ever 5th post or so on my timeline is from someone I do not follow, either "people you follow follow this" or "might be interesting to you" crap.
It's almost always drama, politics, provocations, people screaming at each other, or a mix of those things.
I can vividly imagine what the timelines of casuals users look like...and it becomes obvious why social media are such hubs for hatred and perpetual drama.
There is little "to solve", because the biggest problems of social media are explicitly created by social media companies.
Or as someone would call it whose business it is to manipulate you and to make you miserable (like the devs at Twitter and Facebook): "creating engagement".
Allow users to properly curate their timelines. Then we can at least take the claim that social media companies actually want anything to improve serious.
