One of the many cool things about the Metaweb is that it functions as a vast bottom-up collaborative filtering system. RSS feeds represent perspectives of publishers. Because feed publishers can automatically or manually include content from other feeds they can "republish," annotate and filter content. Every feed is effectively a switch, routing content to and from other feeds. You are my filter. I am your filter.

Entire communities can collaboratively filter information, in a totally bottom-up way. The community as a whole acts to filter and route content in an emergent fashion, without any central coordination. On top of this sites can then provide value-added aggregation and information-refinery services by tracking memes across any number of feeds and then repackaging and redistributing them in virtual feeds for particular topics or interests. And these new feeds are fed right back into the collective mind, becoming raw materials for still other feeds that pick them up.

What we have here is the actual collective consciousness of humanity thinking collective thoughts in real-time, and we get to watch and participate! We are the "neurons" in the collective minds of our organizations, communities, marketplaces. Our postings comprise the memes, the thoughts, in these collective thought processes. Already the Metaweb is thinking thoughts that no individual can comprehend -- they are too big, too distributed, too complex. As the interactions of millions of people, groups and memes evolve we will see increasing layers of intelligence taking place in the Metaweb.
