Maybe I'm not the best person to remind this, but reminder that you can join to different instances than the main one, maybe according to your main interests. It's also a way to avoid overloading the main instance. #TwitterMigration
I'm not the best person to remind this because I'm in the main one. 
I tried to search one that could fit with my interests, but I have a large list and it feels difficult to find something appropiate. Anyway, I'll probably look again, as my Pixelfed account is already in a small instance. :-)
