Is DDG really that much of a name brand outside nerd circles? Maybe I just have weird friends, but almost no one I know IRL has ever heard of DDG, while quite a few have heard and used Bing.
First you get the nerds, then you get the nerds friends, then you get the friends of friends, then you get the parents? :P
