I made a simple search now and found an interesting (new?) search engine called Blekko, The "Slashtag" Spam free Search Engine.
What I learn is that as a user, YOU can personalize the search results based on your preference.
You actually list websites and search in them based on keywords.
I think this might be a good search experience, only if many users bring their interests etc.
I guess that Google/Bing try to automate this option for you as a user.
