The audience on the Web has certainly changed, expanding in directions, defying one's imagination. There are surely far more folks interested in the behavior and mathematical properties of elementary particles today than there were in the early days. At the same time, there are also vastly more people interested in sports activities. Go to any of the major sports league Web sites, and you'll find lots of content. Contrast for example the amount of content, with what was provided say 25 years ago, in the deluxe souvenir booklets one could buy at the ball park for more than the price of an admission ticket.
Presentation is an important part of the delivery of information.
Presentation is not easy, and the underlying technology is far from easy. The Web is growing, evolving, and addressing these needs. Despite technology challenges which are far greater, the Web is responding to these requirements at a remarkably rapid pace. That is up to its viewers. Ultimately it is content which meets viewers' interests and needs, best presented in a useful and satisfying manner.
