I tried DuckDuckGo a few times since it launched. Every time I wanted to like it, but it had a few shortcomings: the results weren’t quite as good as Google, or it was a little bit too unfamiliar.
I tried it once again this week, and I think it’s now good enough for me to switch to it permanently. Google is full of spam right now, it looks like Google refuses to ban content farms like Demand Media which operate eHow & Cracked. This switch to DuckDuckGo has more to do with Google Search deteriorating than DuckDuckGo giving me something new.
