accessing the "collective intelligence"

Commenting on George Por's article, Steven Cohen discusses the value of blogging and other tools supporting collaboration in building a collective intelligence.

While we have many blogging and other social software tools that enable the 'creation' of the collective, how do we harness the "collective intelligence" once it is 'there'/'built'? It would seem that other tools would be needed to enable quick and relevant utilization of the collective intelligence. So far, it appears that the blogging tools have done a great job enabling the representation of the collective intelligence. They lack the function as enablers for utilizing the available collective knowledge.

It seems that the next wave of social network and collaboration tools will/should concentrate more on the function of finding relevant and appropriate 'intelligence' somewhere in the collective pool. Needless to say that search engines are not best suited for this type of activity since they concentrate primarily on topical relevance and do little to nothing about spatial, temporal, methodological, contextual, process, and task specific relevance.
