Duckduckgo

Duckduckgo searches the internet without all the annoying advertising and creepy tracking you get with other search engines. If the right to privacy is important, click the image above, or right here to try it. 

Oh, Duckduckgo also has special doodles, like this one… 

for December 21st, 2012 (when the world was supposed to end), and…

Minecraft!

SweetSearch

In contrast to Google's embedded advertising and tracking, SweetSearch "searches only the 35,000 Web sites that our staff of research experts and librarians and teachers have evaluated and approved when creating the content on findingDulcinea. We constantly evaluate our search results and 'fine-tune' them, by increasing the ranking of Web sites from organizations such as the Library of Congress, the Smithsonian, PBS and university Web sites."
