Our bodies generally do a pretty good job of sending molecules (like blood thickeners) where they are needed (like the site of a wound) and not where they aren't needed (like in our brain).  Our body's circulatory system for molecules is like society's electronic ideastream.

For sustainable use of either molecules or ideas, explicit awareness of the multi-layer structure of our communities as well as the scope of a given communication is crucial.
