Probably a very good move... Yahoo + Microsoft does not equal Google...
The thing about the Web is it's very fad driven....
Remember when Alta Vista was the "hot thing"....Boy you are old!!
Remember when Google was just a secret site for the terminally hip...?
Well now it's being used by Grannies with bad hips...!
This too shall pass... Like Grandpa's kidney stone... Google will meet it's rival someday....
