Olivier has some good thoughts about the illusion of the Internet infinity:
"Next time you discover a great site that appeals to your interests, think about sticking to it in the future. Participate in its growth, if only by promoting it to your friends. Assuming that Google will always pick up good stuff for you is dangerous, because Google doesn't create anything but a collection of links. Always on the move nomads don't create cities, yet it takes more than temporary tents to host and grow great sites. The Internet as a whole might feel infinite, but don't take for granted there are and always will be an infinite number of alternatives to the sites you love."
