Google currently is the most successful search engine. In fact, the verb “google” has made it to the Oxford English Dictionary. The reason for its success it quite simple: it is fast, it has a clean interface and it almost always gives you the results you are looking for. Compared to the alternatives when it started (1998), google was by far the best.
But now it is 2011, and times have changed. Google has evolved, and so have the competitors. And, more importantly, new alternatives have arrived. One of these alternatives is DuckDuckGo. And I like it.
