This is a good idea, IMO, for the same reason why I often read book reviews on Amazon. I'm trying to answer, Why read (thing that everyone keeps talking about)?
Here's some for me personally:
Why should I study
Nietzsche?
Zen Buddhism?
Austrian economics?
The R programming language?
RxJS?
Of course I could go to wikipedia for these, but if you've got a better way of dispensing this information, I'd love to know what others are curious about too.
