Bluesky was easier to sign up and less confusing to use. It had a much better mobile app. A lot of pro newsies came to Mastodon and were roundly ejected and abused, so they up and went to Blurdky instead. That was a major shooting your own foot moment for Mastodon because those newsies would have brought engaged audience. I saw people celebrating at Mastodon when news reporters up and quit. Idiotic. I hope the Lemmy community doesn't repeat that mistake.
