Anjo has an interesting thought on weblog mapping:

“It gets more interesting, as any textbook on networks does, to draw the analogy of graphs with a system of pipes that carry liquid.

Is this analogy useful in the context of weblog communities? Perhaps it is. Imagine that weblogs are connected by a system of pipes to other weblogs where the size of a pipe is proportional to the number of links. Imagine that someone pours some water into her weblog. The weblog community is now defined to be the bloggers who get wet and wetness is an indication of participating in the community.”

Reminds me of Chris’ raindrops and pools… all this water!
