The big difference is that on Bluesky, I don't have political content shoved down my throat by force, and can just focus on stuff that I am on social media for - my interests, hobbies, scientific research, etc. I got on Bluesky a long time ago when it was still invite-only, and used it parallel to Twitter, but just can't be arsed anymore when it's all about American politics, ideological and cultural wars, and everyone hating on everything and everyone else
