I frequently see these questions in the close queue flagged as opinion-based. I have mixed feelings about such threads: overall, I think they can be useful if people explain their answers (several threads on here about this point, such as this one), which is not required, unfortunately. But a big problem is that they depend much more than other questions on the OP, which makes them less applicable to a general audience.
On the other hand, I don't feel super comfortable immediately closing them as 'opinion-based.' I don't disagree that a book recommendation is inherently subjective but it seems like part of the nature of the question, not as a fatal flaw. I think closing a question like this as opinion-based is appropriate, as there are too many factors and it's clear 'natural' depends on perspective. Maybe I'm wrong.
I guess I'm asking:
- What do you all see as the role of such questions?
- Is it ok to close them as opinion-based?
