Not that it is not interesting but I would like just a tad more variety on the front page.
Edit btw for those who are wondering the two communities I started are https://lemmy.world/c/newmusic and https://kbin.social/m/musicfeedback/microblog (not sure if I have the links correct for people)
Every community needs to be federated separately, but instances can defederate entire instances. To federate with a community you have to search for it from your instance.
