But even by that definition, the web isn't a single application, it's many applications, some of them compartmentalized (search, social), some of them not (email), and some in between (websites/blogs). If an application were centralized, I would expect a single provider you had to use, but instead, where it at least compartmentalized, you have a group or providers. Can you name a single service/application that you expect more than 5% of people use that has only a single provider? For search, you have Google, Yahoo, Bing, and other smaller players. Google is dominant here, but still has less than 68% of the market. For social, Facebook is the dominant player, but you yourself used a different social network to communicate on this subject, and there are many other providers with popularity that ebbs and flows. It's the same with anything I can think of. I'm not sure how this is considered centralized under any definition.
