The Web is a Millennial. It was first proposed twenty-five years ago, in 1989. Six years later, Netscape’s I.P.O. kicked off the Silicon Valley circus. When the Web was brand new, many computer-savvy people despised it — compared to other hypertext-publishing systems, it was a primitive technology. For example, you could link from your Web page to any other page, but you couldn’t know when someone linked to your Web page. Nor did the Web allow you to edit pages in your browser. To élite hypertext thinkers and programmers, these were serious flaws.
