18 years ago today, the very first World Wide Web Conference started with a Welcome Receiption at the restaurant of CERN at Geneva, the European laboratory for particle physics, where the Web also started a few years earlier. The Web (or W3 as they also called it those days) was still some kind of project, but everyone of the 380 participants at the conference knew that they now were taking part in something that could change the internet as we knew it before.
