When Bing first arrived, I set my browsers to it as a default to see how it would go. It didn't last a week. More recently, I set DuckDuckGo as my default. I haven't had any problem yet, and today, it sealed the deal. I searched for the Add-PsSnapIn PowerShell commandlet, hoping to find a way to make sure that was I was loading wasn't already loaded (#ifndef, if you will).
Did I mention that DDG does not track you & your searches like Google does? I just can't see myself going back to Google for search anymore, and am glad of it.
