I was thinking yesterday about the first time I noticed the web.  It was 1995 and Yahoo! was still "Jerry and David's Guide to the World Wide Web." At the time I was a writer, and the Internet struck me as the perfect way to talk to readers without all the fuss of contracts and editors, not to mention dead trees. It was clearly a better way to communicate.

Since the beginning of human history, people have sought ways to express themselves through the written word. (If Socrates had only had a blog!) But at no time in human history has there been such an accessible and pervasive medium as the Internet. Anyone can post anything at anytime and potentially reach thousands, if not millions, of people. It may well be humanity's greatest invention.

It's taken a few millennium to get these words up here on this screen. This is a brief overview of the journey:
