When I switched to DuckDuckGo last year I read an interesting comment from someone. The basic idea was that we have all become so accustomed to Google's results and the manner in which we use it (i.e. the way we define our search terms) that it is actually we who must be willing to reprogram our search practices if any competitor is to have a chance to catch up.

I'm not sure if I buy that, but I do believe if we don't commit to alternatives it will be next to impossible for alternative search engines to get as good as Google with result quality and relevance. Google simply know too much about me and has performed so many more searches for a rival to outperform them. I still use DDG's 'g!' often but I feel like I'm doing my part to help DDG get better for me and other users.
