That said, I don't think people are searching for "search engines" on Google. I think people are like me in that they use Google as an address bar.
This make them very nimble and responsive to any competitors who dare to compete with them.
Google is like a sumo wrestler. Despite the appearance of fatness, it is actually very fast, strong, and healthy.
(P.S. of course they eat a lot of their own dogfood---so they are not the right employer for everyone.)
MSN is the default start-page in IE8 and that is being whittled away due to the anti-trust.
In the past 6 months that more and more of the links on the homepage link directly back to BING search results.
From a UI perspective, this is not ideal and to see such low gain #s despite these efforts is eye opening about google's dominance.
I'm using it because Bing has a great flight search and comparison, also their video search is pretty good too.
