Mastodon is a social media platform similar to how Twitter used to be before being bought by Elon Musk.  It is generally a much friendlier and more welcoming place than Twitter, and best of all it does not have any shareholders who can choose to sell to a billionaire looking for a vanity project.  If you liked the idea of Twitter but hate what Elon Musk has done to it, it’s worth checking out Mastodon (my profile page is here).
