Do you also apply this logic to books in a library?
How do you choose which ones to read? Do you read all of them?
I think if you don't have time to read all of the books and judge them on their merits, then you shouldn't be participating in an activity like reading books.
If I'm interested in a book, I tend to read user reviews. A "351 people said this book is great" note won't help me much. I do the same thing for electronics. And most other things too, when the number of choices isn't very limited already, come to think of it.
