I don’t do “Twitter style” social media much but when I did use my Mastodon account I found significant engagement. On Twitter my posts were invisible, but on Mastodon people found, liked, and commented on them. Conversation were good as well.
I was a beta tester for BlueSky and I found the same “invisibility” problem there. Same posts on Mastodon, Twitter, and Blue Sky and only the Mastodon ones generated responses or any acknowledgement for that matter.
