Anyone who uses Yahoo mail gets Yahoo news, sport, weather etc. shoved in their face every time they check their mail. From there people are linked into a network of stuff including search. And Yahoo mail by the way is massive - I can't remember the actual status but they are a multiple of any of their competitors in size and google is a tiny small fraction. I think people underestimate the importance of this just because email isn't seen as sexy these days - but it's eyeballs, and very sticky ones (sorry for image :-) ), they come back regularly again and again - people with lots of history in their Yahoo mail are pretty much never going to leave.
