Search Engine DuckDuckGo

I just came to know about the search engine DuckDuckGo, perhaps, some of you may know about it, already...

It promises these features:

• Way more instant answers.
• Way less spam and clutter.
• Lots and lots of goodies.
• Real privacy.

Search results are gathered from crowd-sourced sites, such as Wikipedia, Yahoo! Search BOSS, Wolfram Alpha, and DuckDuckBot (its own web crawler), in order to pad its "zero-click info" boxes with topic summaries and related topics.

It professes a privacy policy that does not store IP addresses, does not log user information, and only uses cookies when necessary.

Anonymous and encrypted searching through Tor.

It has been voted as one of the Top 50 Best Websites of 2011 by TIME and PC Magazine. You can check it out at www.duckduckgo.com
