I just did a search of previous threads here, after a day of looking up information in search engines other than Google. My try-out of other search engines came after trying Bing for a search, and seeing Bing invite me to take its challenge of comparing its search results to Google's. (For all five of the searches I tried, I preferred Google's results.) I tried a bunch of other search engines, including some I hadn't tried for years, once that got me curious.
What do you think? Do you regularly use a search engine other than Google? Why do you like it? What does it do better than Google? What's a good search engine to use regularly for looking up varied information?
