DuckDuckGo
Hate the new changes with Google?
Try DuckDuckGo. DDG has been my default search engine for almost half a year. It offers users more privacy and integrates well with major browsers.
DDG doesn’t track you at all. http://donttrack.us/
Off course when DDG results are not enough for me I’ll change to google which is easy by using !g on DDG.
