I've been on #Mastodon for only a few days and I already feel less anxiety/stress over here than on twitter/X. I love the fact that both Mastodon and #Bluesky are overall leftist/left-wing. I'm so glad the future of social media is decentralized (e.g. #ActivityPub, ATProto, Nostr, etc.).
Twitter was never a healthy place with all its silly algorithms and encouragement of confrontations. I don't know which platform US society mostly resembles, but I hope it eventually resembles Mastodon, etc.
