The departure of Terry Semel, the return of Jerry Yang and the ascent of Susan Decker haven't brought much-needed stability to Yahoo!, which announced that it would continue to shuffle its top executives.

Decker, who serves as Yahoo's president, announced that Gregory Coleman, the company's global sales EVP, will leave in February as his responsibilities will be folded in the new Global Partner Solutions division.

The Global Partner Solutions division, which will be responsible for relationships with all advertisers, ad networks and publishers, will be led by Yahoo EVP Hilary Schneider.

In June, Yahoo lost its chief sales officer, Wenda Harris Millard, when she left for Martha Stewart Living Omnimedia. Decker began restructuring the company's sales team at that time.

"I know there have been many changes at Yahoo over the last few months, and I know that change is not always easy," Decker said in a statement. "I am confident that we are putting the right people in the right positions to focus on the right opportunities."
