Have you ever thought that the internet lacks, well, a degree of culture? That there's too much content that is irrelevant, superfluous, wrong, or pointless? Would you like a portal site that points you to lots more interesting, educational resources?
If so, then check out Open Culture, at www.openculture.com. It comprises links to lots of free courses, books, audio books, language learning courses, videos, textbooks, and loads more besides.
Access to the site, and to almost all of the content, is free. Though there are some optional extras, which cost money, such as the ability to print out chapters from certain books (you can still read them on screen for free, and copy the text to your clipboard).
