Is it time to stop using Google?

I've always been a devoted "Googler" from the very first time I used their search engine a few years ago. However, after reading this article I've decided to start exploring other optinos. I've found two decent engines: iXquick and perhaps this other one, Clusty. Google did refuse to hand over information to the government earlier this year but I don't like the idea of them storing that much of my personal data.
