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)
Just to answer this part, the pending subscriptions (mostly a problem on lemmy.ml communities but sometimes elsewhere too) seem to be mostly a visual bug. I have a ton showing as pending but posts from them turn up in my feed so I’m clearly subscribed.
