Uh, what a way to make things sound needlessly complicated. He could have just said "the Internet is a way for people all over world and in far flung places to talk to each other".
What's harder to explain is the emergent behavior that comes from that. I like to think of this as "meta gaming".
Generally when people start playing a new game, they don't care much for picking the optimal team/items/tools, they just play to have fun. As they play more, they recognize that some combinations are stronger than others. Some people will theory craft those combinations.
Over time, the general population will inherit those combinations, or perhaps build against it. That's kind of like the Internet before and the Internet now, but on a much larger and more complex scale.
Finally we know exactly how it works and its based on an RFC system. We may not comprehend the the societies built on top of the internet.
I do believe a blog is a form of search query.
