First, there's Nutch, an attempt to create an open source search engine on the basis that other search engines display search results with some kind of ranking, but don't explain what that ranking is. Nutch is out to prevent the Man (commercial search engines) from taking over and turning searching into a paid service.
     Next is Namebase, a sort of anti-conspiracy group that collects documents on just about everything, Including Google. This goes right along with GoogleWatch, who targets Google, citing them as Big Brother, trying to build a case that Google's monopoly, algorithms, and privacy policies are undermining the Web.
     And then there's Scroogle, a listing of pages missing from google's top 100 search results for a given term since November who encourages you to help end Google Bombing by contacting Google executives.
