Charles Schultz's philosophy & future of the Internet

Came across this nice article: http://www.rogerknapp.com/inspire/schultzphilosophy.htm.
I think this article very aptly represents the recent trends of the Internet. Of late, social networking sites & sites with user developed content such as photos & blogs have been the most popular sites.
So, what has led to this demand for such community based sites? I figure out sociological & technological reasons for this.
Technologically, as memory becomes cheaper, websites can host more users for much lesser costs.
But at a sociological level, I think its our growing passion to share our world with our near & dear ones and also our excitement to know more about the people we care.
