Which search engine do you use

I think the results of this poll will be 100% Google, but that makes me wonder…is something superior if no one checks the competition. I saw an article today that says that Yahoo! has a larger index than Google. I actually have Yahoo! (my.yahoo.com) set as my start page in my browser, and I use yahoo mail, but for some reason I never use their search. It is just reflex to go to Google for my searching, but why? I have decided to give others a try. I am going to use Yahoo for the rest of the month, and then try out MSN. I might even try out the others, but for now these are the ones everyone talks about.
