When I think of privacy, I don't think too much of the NSA. Rather, I am much more concerned about Google storing every search I do to show me more relevant ads, because, hey, I'm not comfortable with being sold to advertisers. Now, if I was really paranoid about NSA or wanted to hide stuff, I would use much more radical measures - say: using linux Tails, only browsing with Tor, and possibly from a public network whenever possible (in order to use a different IP each time). For me, DDG is a decent middle ground. I suppose the NSA could track my search history if they really wanted to, but meanwhile it's a bit harder for them and I am less targeted by advertisement.
