Some, or perhaps nearly all, search engines narrow your results based on what they think you will be interested in. But this leads to a problem: You may miss out on new things because the search engine has filtered them out of your results. Instead of helping you find things you want to know, the search engine's filtering system has thrust you down some path based on your earliest inquiries, stranding you in a part of the information forest that looks inviting but omits the surprises you really do want to see.
In other words, using Google, Yahoo, or Bing forces you to have a blind spot in your thinking and searching.

The search engine DuckDuckGo solves this problem by not slanting your results through the storage of past searches. In my short (very short) tests while writing this entry I was very pleasantly surprised. Unlike Cuil, the supposed "wonder search engine" that produced amazingly bad results after a while, DuckDuckGo is pretty, produces Google-quality (or Bing-quality if that's the way you roll) results, and had some very cool extra features.
Five stars.
