Edit: some people have referred to Area 51 being the place to ask this kind of question. Can this question be moved there by someone?
Edit 2: people see problems with this proposal: it would be too subjective, commercial interest of publishers, spam, etc. But maybe we can think in a positive direction - there are many people who benefit from discussion on what resources there are on a certain programming topic. There are excellent blog posts out there on certain topics. How could we build a site that helps solving the "what resources can I use if I want to know more about programming topic X?" The answers could be: this and that blog post, this and that chapter from books X and Y. I'm sure a lot of people could benefit from such a community powered index, even if the answers are subjective. What if we took that for granted? Think in possibilities instead of problems.

It saves time and students get used to actually reading these books, which is a good thing. However, every time I ask something about programming books on Stackoverflow, my question gets closed. I think there should be a site dedicated to programming books/resources/tutorials so people can happily ask there, without getting the disappointment all the time from the rigid "the question is not suited for this site" replies.
Examples of questions I asked on Stackoverflow which are suited for this idea:
