Quietly ousted last August after seven years at Yahoo, former ad-sales chief Gregory Coleman has been hired as CEO of ad-targeting startup NetSeer. Coleman's main job at Yahoo was to protect chief sales officer Wenda Harris Millard from meddling managers while she generated revenue. Millard left for a new gig as a president at Martha Stewart Living Omnimedia last June, giving the company enough time to see exactly how valuable Coleman was. At NetSeer, he won't have to deal with meddling, indecisive bosses any more — he's earned the right to be that meddling, indecisive boss.
