[Air-l] Fwd: politics and ideology of search engines

Perhaps the list can give me some suggestions for discovering more about the politics and ideological approaches of specific search engines. I'm familiar with Hargittai's work on channeling content online as well as Introna and Nissenbaum's research on the general politics of search engines. However, does anyone have any knowledge/references about the specific ideologies and politics that affect how search engines such as google, excite, goaskjeeves and yahoo index particular web sites?
