In March of 1989, Tim Berners-Lee, a contractor at CERN, wrote a powerful essay titled: 'Information Management: A Proposal'. This document married the concepts of Hypertext and the nascent Internet to create what we know today as: the World-Wide Web.
On the original proposal, Mike Sendall, Tim's boss, wrote these words in the top margin, tacitly giving Berners-Lee permission to move forward with his proposal - and create the most quickly adopted, and revolutionary, form of communication in human history. 'Vague but exciting,' indeed.
