The fediverse can be tricky to sign up to and once you are there it is hard to find communities/interest to subscribe to. But I am learning how. And it is working for me. Another fediverse user gave me a webpage that helped me find more communities to join. Lemmy Explorer you can select the Home icon at the top to set your home federated server. Kbin.socal for me.
I even found a Baldur's Gate community and a Calvin and Hobbes community.
I was part of that subreddit and welcome them to the Fediverse. But I'm in kbin and my efforts to join them are not working. Hope there is a fix for this soon.
Side question: Is there a website with a list of all interest/communities and its address so we could just search that website and add all the sites we wanted to kbin?
Facebook/meta makes everything terrible.
