IIRC (it's been a while), Yahoo's roots are the librarian approach to the problem of organizing the world's information: classification, taxonomy, Dewey-Decimal, directories and subdirectories, whatever. I prefer Google's approach to the problem (massive silicon replacing wetware). But, being much lazier than the average slacker, I could be wrong.
