A fantastic piece by David Weinberger on the changing uses of the internet—apparently in contradiction of the internet’s original architecture.
Some folks invented the Internet for some set of purposes. They gave it a name, pointed to some prototypical examples—sharing scientific papers and engaging in email about them—shaping the way the early adopters domesticated it.
But over time, the Internet escaped from its creators’ intentions. It became a way to communicate person-to-person via email and many-to-many via Usenet. The web came along and the prototypical example became home pages. Social networking came along and the prototype became Facebook.
