Yahoo and Facebook Not in Search Alliance Discussions - Kara Swisher - News - AllThingsD

A timely search market reality check, after some breathless speculation about Facebook and Yahoo search partnership permutations (e.g., see this Business Insider article)

"Could the pair do more in terms of sharing among its users? Sure! Could they more tightly integrate services? Yep! Could they do something jointly related to advertising? Why not! But will they build a search engine together? Not likely.
Indeed, I am not even sure what such a thing means, since it would now be nearly impossible to execute, given Yahoo has outsourced its core search technology long ago to Microsoft and has been largely focused on improving search experience since then."
