Kevin Lynch has managed to say in one paragraph what I've struggled to explain to people:
The two main ways I find information on the internet today is by searching and reading blogs--blogs are another view into the world's information and we're just starting to understand how we can best visualize the connections across blogs and track relevant information as it's happening, whether it's through DayPop, Technorati, blogdex, or maybe something along the lines of power curves. Blogs provide the serendipity that is largely missing from search, while also providing the consistency of a single, current stream of thinking from a variety of points of view.

Well, he doesn't actually break it. He merely points out the built-in brokeness that the rest of us have been [wrongfully] conditioned to just deal with.
