Just for grins, I was looking at the slides of a talk I did ten and a half years ago (March 1994) about this new thing called the world wide web. Pretty much everything on my "future of the web" slide came into practice pretty quickly, with the possible exception of a general-purpose proxy architecture to keep sites from getting slow. Some of the p2p crowd are working on things like this now, of course, but there's still nothing in general use.

Remember when Adam Curry's MTV.COM was the coolest thing around?
