@joachim Best ways I've found to get started:
1. Check out the local timeline.
2. Search for and use hashtags about things you like, e.g. #clowns #clouds #weirdfeet
3. Find people with similar interests to you and traverse their following / followers graph.
@zimablue @joachim Ah, yeah, also this: https://www.movetodon.org/ (I haven't used either of these but I've heard of people using them)
