I like the idea of recommended books appearing on book pages. As you say, there are different ways of doing it.
A recommendation section could include books that are:
- not on any of your lists
- have an average score of 3+ stars
- are good for language learning
- have a similar natively level (give or take a couple of levels)
- also have furigana (if applicable)
- (possibly) are the same type (manga, light novel, etc)
- are similarly entertaining
- people who liked this (4+ star rating) also liked…
- similar natively level or any level up to the highest level on your finished list
- share content tags
I haven’t thought it out, but the individual entertainment/language learning ratings may be useful here, too.
I think this leans towards the entertainment aspect, but doesn’t really address the language learning aspect of the suggestion.
