Strongly disagree. Bluesky is extremely American-centric and basically just a bulletin board of “hot takes”. I find Mastodon much deeper, more engaging, and international. I’m glad I deleted my BS account and replaced it with Mastodon.
edit: However, I was never a Twitter user in the past
Mastodon exists, currently, because enough people like it (and some of those people, myself included, like it in part because it’s less Americanized than BS). Perhaps a Twitter replacement should be better than Twitter. Maybe for many people Mastodon is an improvement.
