I use Bing/Yahoo for most initial searches. If I can't find what I'm looking for in 2-3 tries I switch to Google.
What I find way to often with Google/Bing/Yahoo is that I often get VERY old pages in the serps for TIME SENSITIVE stuff.
If I'm looking for a 2011 event, I really don't need a page from 2008, especially when that page ranks better than the page for the 2011 event.
That often happens even if I use a +2011 -2008 -2009 -2010, etc.
