I've noticed a trend in goodbyes from Yahoo: All the departing executives claim to "bleed purple." If so, Yahoo blood is thinner than water, because there's little love for president Sue Decker's new regime. Jacki Kelley is the latest executive to flee the sales side, now under Decker ally Hilary Schneider. She headed up sales strategy and worked on Yahoo Travel, one of the first areas of the portal to try to integrate banner and search-ad sales. Kelley is joining former Yahoo sales chief Wenda Harris Millard at Martha Stewart Living Omnimedia. This isn't just another departure, in other words — it's a show of loyalty.
