I have recently tried to check around goodreads alterantives and I came face to face with these ISBNs and ASINs and how these are a hot mess. There's really no truly open metadata source that is "enough". App developers often depend on proprietary sources and sadly those are the ones which are more complete and go their own way for every source. How did you deal with that?

I also finally tried "Thinking, fast and slow" recently and realised it was absolutely not for me. Even the audiobook version didn't cut it. I found it completely dry and trite. I am not trying to offend anymoe (esp. with "trite"), and I am aware how storied and awarded the author is – to me it just came across as "yet another self-help kind of book" sadly. But then a clear lack of fiction for a long time in "top all-times" puts into perspective why that book is up at the top. I think the general hn reading-taste is quite different from mine. Also, it's not about what was book about, because I never reached that, it was rather how it was written.

Any plans to add some sort of tag/genre to search feature?
