I agree this is a really good use case for nostr. Certainly not jammed in. @nprofile1q... its essentially what youre trying to do with the ratings system but supercharged so that its "intelligent" enough to be able to specifically tailor your recommendations by comparing your personal taste profile against other individuals by assigning scores to various categories (genres for example) based off a users actions. WOT essentially allows you to build personal profiles that follow you beyond just a single app and compare with other similar users. It has powerful implications across the entire valueverse.
