Interesting link from http://www.scripting.com: OpenCola Technology Overview

Brute-force computing solutions are not appropriate for many of the problems facing the Net as it expands. OpenCola represents an approach where simple technologies are used to enable a particular side of human nature: the tendency to form communities of interest. As an enabler of activities that people pursue naturally, OpenCola puts humans back into the loop of finding and refining resources on the Net, while not presenting this activity as "work". The result is projected to be an internet that presents itself to the user as an organized collection of relevant documents, instead of an amorphous Web.
