Actually this is quite encouraging:

But you can criticize pretty much every tech executive for similar issues. Larry Page of Google is also shy and socially awkward, Steve Jobs was a micromanager who made some bad hires, Jeff Bezos has made huge gambles and lost, and Bill Gates would rip his engineers to shredsif he believed they weren’t up to par.

Admirers of these men often overlook their idiosyncrasies because they got results. And that is what Ms. Mayer is starting to do. Since her appointment, Yahoo has released a string of apps that have won critics’ accolades. Yahoo’s properties now attract about 550 million mobile users a month, and its growth has outpaced the industry average.

The research firm eMarketer says that Yahoo is poised to surpass Twitter for third place in the American mobile ad market (it remains far behind Facebook and Google). Ms. Mayer’s acquisition of BrightRoll, a video ad company, could add hundreds of millions of dollars to its revenue this year, and the purchase of Tumblr might begin to pay off soon.
