I have a friend that insists that "Mastodon is Twitter with HOAs", but I do not agree with it. I am writing my own blog post about Mastodon: https://bristle-tachometer-5db.notion.site/Yet-another-Masto...
I personally enjoy being part of a community, getting to know the people around it, and get to chat about it in small discussion groups. I hope the Fediverse continues to evolve, and helps to build communities. Twitter has become too much about building an audience.
