Nice post! Enjoy your blog's overall aesthetic too. Perhaps correlation in sense of style, though, as I also used RTK to learn to write Kanji, loved it, and now, ~15 years after that escapade, am kind of in a similar bucket (can write some characters, but mostly just read). I still think RTK great overall method and would do it again!

Also, shoutout to Fabrice, creator of Kanji Koohii -- that was my first foray into SRS back in ~2007/2008, after which I found Anki (pre-mobile).
