I see your point but need to say that I find the curation of B & N to be decent, including the "technology" section -- you can find a good mix of beginners and advanced level books, and they are often up-to-date.
And slightly off topic -- libraries (both public libraries and university libraries) can sometimes be exactly opposite of this. Whenever I see people say "find a book from your local public library" I know they never been to one and carefully check out the catalog themselves. New books don't arrive on the shelves until several months or a year later, and libraries rarely get rid of outdated books that teach you to learn Windows 7 or C# 6.0.
