I have been getting better search results using MSN than I have with google.
I never run searches with MSN, even when I don't find something with Google (which is very very rare).
But even if it would give me better search results (and I would be surprised if it would), Google > Microsoft in MANY respects.
http://google.org/ being ONE. Google are just nicer.
Until it gets to a stage that Google often gives me shitty results that aren't much use to me, I'll stick with them. And then - I'll try Yahoo search.
