Twitter has the highest signal/noise ratio of any social media platform, for me. I've curated it so 1) I don't follow people I know in real life so I don't have to deal with their completely different ways of using Twitter 2) I follow mostly historians, cinephiles, and art accounts 3) I pay for the Twitter Premium service so I can rearrange the UI so as to make it hard to reach the wasteful and noisy "explore" page. I get a stream of illuminating long threads about history, tidbits about films from now and the past, and tons of art from all sorts of time periods. I also block words for topics I don't care for any more such as "Marvel" or garious political figures.
My Twitter posts are just quotes that I post mostly for myself, for the future. The hardly get any likes and I don't care if they do. People-pleasing is a dirty and dangerous business.
If I could get rid of the explore page, I suspect my Instagram would be similar too. I mute most people I know in real life except for a few treasured friends who post fun, wholesome things, who aren't trying to show off or induce fomo. My actual feed is more photographers or people who share art/design stuff. So that's all good stuff.
