This is the title of a talk I gave on May 7th, 1996 (over ten years ago!) at the Fifth International World Wide Web Conference, at La Défense in Paris. It won a gold medal from the Mayor of Paris (one of two at the conference thus distinguished) which I display in my office; I worked awfully hard on that paper. I wanted to cite it recently, but the WWW5 Web Site has been AWOL the last few times I’ve tried to go there. Coincidentally, I ran across the conference CD in a recent basement re-organization. So I’ve staged it here: Measuring the Web. It’s no more than a historical curiosity now, but it’s a history that’s not that well documented. Plus there are some pretty pictures. Occasionally I wonder what might have happened if I’d been smart enough to follow up on the significance of the notion of “visibility”.
