Ask HN: Book Recommendations

Where do you get your book recommendations?

Do you subscribe any value to all these 'Must read books' lists or what Bill Gates (or other famous person) may say they read in a blog post? Do you assign any value to a list put together by some random person that says a famous person recommends a particular set of books?

In other words, do you feel more inclined to read a book that has been endorsed in a list by someone famous?

Do you just rely on reviews from Amazon, Goodreads etc?

Lately, some of the most interesting books I've found have actually been through HN threads where a user mentions a book relevant to the topic discussed, usually by including a summary or short excerpt from that book.

Your thoughts?
