I'm glad that you're feeling somewhat better and are on the mend!
Bringing more people on board for moderation is definitely a good idea, as is delegating administration. I think it's clear to everyone who keeps up with all your updates that the coding/development is where your heart lies :) Absolutely prioritise these things; reddit's IPO is in a week and a half, and I wouldn't be surprised to see the fediverse, and /kbin, grow because of that.
I'm happy to put my name forward for helping out with moderation (as I'm sure plenty of other people will, too). You've made something special in /kbin, and helping keep it focused and spam-free through moderation feels like the least we could do to help out!
