I don't think its mentioned in the version of the article you linked (good choice on the printed version to link, though): this article is from February 2007. It also focuses on the failures of ex-CEO Terry Semel, not Jerry Yang's current predicament.

Closing argument for the lazy: "At Yahoo, the marketers rule, and at Google the engineers rule. And for that, Yahoo is finally paying the price."

Though it sounds catchy. I dont think the last statement is true. Google is(was) known for its less marketing budget, comparing it with any company would seem the company overspends on marketing.

Just a note: linking to the print version is annoying. The print version is harder to read (in FF anyway) as the lines are longer and there is no border.

So yes I know you think you are being all cool and anti-corporate and stuff but you're not doing us any favors.
