I have always came across this that either Yahoo is much more a better search engine than Google or Google is much more a better search engine than Yahoo! What do you think is? I would prefer Yahoo, because other than it is a search engine web site, it also provide other things to do while in the site. Comparing to Google, Google still does, but we will need to navigate ourself out from the main search page! However, I found that security wide, Google seems to be more secure and able to filter much "junk" sites out than Yahoo! For majority of the contents and the quality, both seem to be at the same level~! what do you prefer most? Yahoo or Google? Or do you go for BING?!?!??
