SilverWire is a tool for increasing socialization and augmenting communication among communities that actively publish content on the World Wide Web. It is designed to build bridges across community boundaries by comparing the works of different community publishers and by introducing members of different communities to each other. SilverWire also provides a way for conventional media companies to better serve these emerging community publications by integrating professionally created information feeds with community publications. The goal of the SilverWire system is to be a Web intermediary that makes communities more aware of other communities doing similar (or interestingly different) things.
