I have created a number of comments on individual grammar items about this, and I’m starting to notice it as a recurring trend in many items. So I’m attempting to start a higher level conversation about that. My latest example that I just ran into today:
This corresponds with the grammar item ～たばかり, but the word subjectively is not present in the lesson anywhere. And it’s not just about that specific word. The entire concept is simply NOT in the lesson.
Why are reviews giving hints that do the opposite of what a hint should do? This hint made me think long and hard searching for grammar points focused on subjectivity, which was exactly the wrong corner of my brain to search.
I would guess maybe this happens as “content creep” over time (the lessons and reviews are updated at a difference cadence, eventually leading to a mismatch). I can appreciate that keeping 1000 items in perfect state is a gargantuan task. But this kind of error is glaring and frankly kind of ruins the entire spirit of the review. Perhaps as a simple fix that can be started in a programmatic way, consider writing a quick script that scans every item and queries to discover if any of the highlighted hint words are 100% absent from the lesson. Anything found by that query probably deserves immediate attention.
