There is a reason we moved from newsgroups, to HTML and browsers to search engines. Each step became a better, more powerful tool to find content faster, more efficiently.
These days so many of the tools we're using are so entrenched, even with some of the changes the author talks about, it would still be a monumental task for people to change.
I mean, look at how bad FB is (on several levels) and look at all the alternatives which allow you to keep your information private and share what you want like Diaspora or Freenet. I tried (repeatedly) to get friends and family to join my Diaspora pod and tried to convey all the advantages of it being private. Nope, nada, no way. None of them ever joined and many just said FB has such deep roots into their lives, giving it up would have a huge effect on their lives, it was crazy.
