The app consistently shows me things that I want to see from the social circle around the people I follow and the topics they talk about. Alternative platforms like Threads are worse at this; the platform I hear the most about, Bluesky, brags about not having this. Maybe the Twitter experience varies by which topics you are interested in, you might get served more slop the more mainstream topics you follow. But the reason I have not quit due to unusability is because there isn't any unusability.
