I'm disappointed to say that I switched back to the Goog just last week. DDG has become markedly better. However, it seems that for some searches they are off on a different axis. For my purposes, the two are almost equivalent, but I found myself going back to Google often enough that I eventually made the switch back. I really want DDG be my default, so I am going to try again, but I'll wait a few more months. Next round, I should keep track of which searches sent me from DDG back to Google and send them along to them. It would be interesting to know what component of my affinity towards Google searches is due to their personalization of results. I don't suspect that it is significant, as I haven't noticed much difference when I am not logged in. I wonder if DDG could provide a client-side plugin that had a similar effect, working on the results that they piped to my browser, without sending anything along to them.
