A search site for every need...

Google seems to be monopolising the search world. But there are plenty of Google alternatives and many of these players offer a different, but targeted search experience depending on the user needs, being them to look for: 

real-time social media search and analysis (SocialMention) ,

user-generated content (Technorati), 

information contained in web forums and message boards (Boardreader)

or demographic and traffic stats (Quantcast).

Search Engine Watch have listed 12 alternatives to Google for all things search, find them here.
