In a supermarket I may go straight to the produce section and feel quite at home, but never stop near the meat. The radio has countless stations to which we can tune in, but nobody expects all of us to be familiar with them all. It's not really very different from a library, or from the book review section of a newspaper. Each tries to cover as much territory as possible, but nobody really expects the visitors, or the readers, to taste everything. It's not the same as a restaurant where we order from a menu because that menu is already focused toward a particular cuisine.
Few people enter a Chinese restaurant with the intention of ordering pizza.
The internet, however, is, by definition, a smorgasbord of almost unlimited cuisines. Today, perhaps the answer is yes. A simple and almost obvious yes. But somehow that answer seems to go against what was considered the vision of the internet only a few years ago. Hypertext wasn't only a technique.
