There is little actual content in present day Internet relative to its size. Look, what is produced on those websites that also tend to carry heavy presentation is not content. Real content is Wikipedia, or Hacker News, or various people and their various topical subpages, personal blogs, up and including stuff hosted at Geocities and Tripod Lycos. What is not content is most of the stuff that's created for money, including majority of today's "journalism". Information that is shallow, false and/or useless, and that exists only to make you click or buy.

90% of for-profit content could disappear just like that, and humanity would be much better off. Every information that is valuable, you can almost always find for free, posted by people who don't try to use you.
