In my search for nice tools that respect my privacy and my rights like don’t being tracked down and so on, I discovered Duck Duck Go.
From their about.html:
DuckDuckGo is a general purpose
search engine like Google or Bing.
• Get way more instant answers
Zero-click info above the links (red box).
• Less spam and clutter
We ban those useless sites with just ads.
• Lots and lots of goodies
Special searches (tech), syntax & settings.
• Real privacy
We don’t track you! (Illustrated guide.)
This search engine was built by Gabriel Weinberg in February 2008 and if you are curious about the architecture, you can have a look here.
It has everything you can expect from a search engine: there is a huge amount of goodies for the geek in you, a Firefox addon is available here, there are tools, plugins and add-ons waiting to be enjoyed!
There is the funny Let me DDG that for you! to have fun of a lazy friend. Click here to see an example.
You can also add DuckDuckGo search box into your web site.
Check out this page if you’re interested about the tracking topic.
Also, don’t forget to check out this page about bubbling.
Finally, if you like it, please help spread DuckDuckGo!
First of all, welcome to the Fellowship planet!
Yeah, I really dig DDG as well
Before that I was looking at Blekko and Cuil as a Google-replacement, but DDG seems to fit me just fine 
Actually, I’m using Seeks as a primary search engine (might even install it myself someday) and DDG as a secondary.
It’s great to see new search engines emerge that value your privacy and some of which even as Free Software distributed services (like Seeks and YaCy).
Hey, hello Matija and thanks for welcoming me in the Fellowship planet family!
Seeks seems an Interesting project. I may give it a better look, for now I stick to DDG.
Yes, it’s really nice to see new search engines (and SN) that respect privacy, we really need them even as a “happy island” to meet other people and realize that we’re not alone.
“Is DDG open source?
Some of it. It’s also largely built with “FOSS”. We also give 10% of our income to FOSS. Check out this years donations.”
Interesting. Shame it isn’t just a clean front end to YaCy.
