Issue Crawler

The Govcom.org Foundation, Amsterdam, and its collaborators have developed a software tool that locates and visualizes networks on the Web. The Issue Crawler, at http://issuecrawler.net, is used by NGOs and other researchers to answer questions about specific networks and effective networking more generally. You also may do in-depth research with the software.This is an excellent tool - Axel Bruns has used it to map David Hicks related blogs for example.
