Searching the search engines

I only know one person who doesn't use Google as their main search engine. She uses Yahoo instead. Google must be making bank. Whenever anyone is using a search engine, they use Google. They always get their results within the first few pages. Sometimes, when someone is doing a really big research project for school, they will reach out to other search engines. Sometimes people will go and use Yahoo. Another one people often use is Ask Jeeves. I remember the first time I learned about other websites. It was a surprise to me that people might even consider using something else. I wonder if those people are making just as much money as the people who work for Google.
