Granted that DuckDuckGo.com is quite a childish name, but then so was Google when we first heard about it in early 2000s, wasn't it? I just switched to DDG recently and feel that not only is the interface fast and minimal (like Google used to be in those early days), but even the results seem to be a lot better (at least specific to the programming topic that I search too often). I'm getting a feeling that some day in future, DDG is going to become as big as Google, if not supersede it.
But a search engine's results are only as accurate as the number of users who search and contribute to it, so its my appeal to people to give a chance to DDG and start using it more and more instead of Google.
