Congrats on the swinging 60’s achievement. As for your post I’d agree with most of it. Especially the bit about mnemonic inconsistencies. Some of the mnemonic choices seem just downright strange. 鳴
Chirp for example has the reading of ’な’ and the suggested mnemonic of ‘nature’. Now to my mind the more obvious choice would have been ‘natural’. Or even your own nananana batman example. Surely ‘nature’ on the other hand suggests a 'ねい’ response.
It’s only a small thing but wanikani is littered with them and I really don’t understand why. I understand it’s poetic licence but why go to all that trouble to devise a mnemonic that is suggesting a sound other than the one you want people to produce? I guess time constraints meant some of the readings were ‘rushed’ somewhat. Or perhaps the author doesn’t put as much weight on exact sound reproduction.
I’m not knocking wanikani. It’s awesome, I’m addicted and the benefits I gain from it’s use are huge. But yeah some of the mnemonics for reading are a little strange and like you I simply use my own.
EDIT: Soon after posting this I stumbled across the new kanji 転
Revolve. And in the interests of fairness and balance just had to share the quite excellent mnemonic for this:
For a man, cars and boobs are what make the world revolve. Without cars and boobs, life just wouldn’t be worth living. The world would stop revolving, and life would just cease to exist for men.
Made me chuckle and I doubt I’ll ever forget the meaning of this (nor the fact that the reading presents the more unbelievable scenario of てん sets of them). Good work.
