You're doing awesome @ernest - I can't express how much your hard work has made a difference to the Fediverse. This is the only software that really bridges the Lemmy / Mastodon divide, and given how new it is and the fact that Kbin's uptime is better than lemmy.world - that's remarkably impressive. Take care of your family, and pace yourself - take a break if you need to, but don't feel like you need to quit because folks expect one man to do the unpaid work of multiple admin teams. Step back and delegate if you need to, but don't step down - you're an excellent leader and the current success of Kbin is proof of that.
@downpunxx Kbin is definitely not dead. These are just growing pains. I believe the bug you're encountering is related to domain blocking. Try unblocking any domains on your block list and you should see the commenting bug go away - this may fix the notification issue as well.
