I never really liked Twitter, either, and joined Mastodon in 2019 for fun. I'm very active in it, now, as I have spent the time curating the stuff I want to see. I interact with watercolor artists, green technology enthusiasts, "good news" orgs, sustainability advocates, and travel photographers. It takes a bit of work to set up, first, but the biggest thing is to search keywords as hashtags and follow everyone you think you might like and interact often with them. You can always unfollow, later.
