Another Yahoo exec leaves the fold. Is Mayer to blame?

Yahoo has lost another top executive to another company, and more are likely to follow suit, says AllThingD's Kara Swisher.

James Carroll, who had served as senior vice president of Yahoo's consumer and global platform group, is taking on a key role at domain-hosting firm Go Daddy, say Swisher's sources. Formerly employed by Microsoft, Carroll was "responsible for Yahoo's content, social and membership platforms and the international delivery of all Yahoo products and services worldwide," according to his LinkedIn profile.

Carroll is a familiar face to Go Daddy CEO Blake Irving. Irving was formerly Yahoo's chief product officer and had brought Carroll on board Yahoo in 2010.

Hillary Frey, formerly Yahoo's news editor in chief, also recently left to scoop up a job as editorial director of news at NBCNews.com. These two latest departures follow the exit of Yahoo Mail and Messenger General Manager Vivek Sharma, who reportedly is taking a position at Disney.

Why all the departures?

Some might point a finger at Marissa Mayer, who was named CEO in July 2012. Since her arrival, she has faced the daunting task of turning around a company that's seen better days, and that means making some sweeping changes.

Mayer has slashed certain Yahoo products that were considered unpopular with the public and unveiled an initiative to spend more money on product development and marketing. She also set a goal to beef up Yahoo's mobile presence.

Some of her moves have been more controversial.

Mayer recently announced a new ban on working from home, effective as of June. That policy change upset some Yahoo employees who placed a lot of value on their flex-time arrangements. Others inside and outside the company also questioned the decision, saying it would limit Yahoo's ability to hire the right people.

In her quest to revive Yahoo, Mayer has to make difficult decisions, and her efforts inevitably are going to ruffle some feathers.
