Twitter has end stage cancer by algorithm--one that promotes rage and attention seeking. As people who are repelled by such things leave, the dynamic is reinforced by the self-selected people who remain and the bots that game them.

Other social media communities exist that, while differing in details, lack this influence and this outcome.

Personally I've found the Fediverse (usually called Mastodon for its most popular client), and of course Nostr, immensely satisfying for this reason. Very different communities with very different norms, but neither suffer (at least in my corner of each) from this kind of perpetual rage bait and "engagement" seeking.

Yes, there is much objectionable (to me) content on both, but it is much easier to ignore as it is not promoted in your face.
