From Google to Yahoo!?
Marissa Mayer really must have been looking for a challenge. Why else would Google’s 20th employee leave the company this summer for its punching bag, Yahoo? The initial focus on Mayer’s Yahoo tenure was largely about… how soon she’d return to work after having a baby. But now that she is back, attention has turned to changes she’s making at the company, including snapping up companies such as OnTheAir to bolster Yahoo’s mobile capabilities. "Hiring the most talented mobile product thinkers and engineers is a big priority for us moving forward," one Yahoo senior vice president said.
