I believe that Rich and Guru both have valid points.

Let's face it, the kids dig Yahoo for many reasons, and they will for some time to come. MSN is all business, and very good at what they do. My impression of Google is still that of an amped up search engine.

However, it should be noted that Rich's statement about the energy that Google possesses not be overlooked. If the Internet were a Serengeti, then Google is no doubt a young lion that walks almost anywhere it pleases. MSN and Yahoo are huge strong beasts that sit comfortably in the shade of their own trees, and perhaps find it annoying that they're being watched from afar by this young intruder, but can any animal really remove them? Many seasons would have to pass for that to happen.
