Back in the day, the internet was all open. You could write your own HTML, and do whatever you wanted. The only limit was how fast your modem was. Then along came AOL, and all the tech nerds decried it as the death of the Internet. It was a walled garden that treated users like idiots, sending them down prearranged paths to the world wide web. But those prearranged paths were guideposts for people who could not comprehend, never mind figure out how to navigate the world wide web. AOL is (mostly) gone today, but many many things have taken its place.
