More likely explanation: The people who post in this thread are more often the ones who get referals from MSN. For me Google WAY outdoes either MSN, ASK or Yahoo. Yahoo does best of those other engines, but when it outdoes google for a page, I worry: think of the visitors I could get if google ranked me well for that keyword... So to the last poster: this is a highly biased crowd. For most people google is the best engine, and that is why most people use it. That simple.
I carried out a comparison of search engine accuracy: check out the results at the blog of my site. You can read it through my profile details (still unable to post links ) Well, it turned out that the MSN is the best and most accurate search engine No joking...
