Another Microsoftie joins Yahoo's new cult of personalityHeavy.com continues to get lighter; Eric Hadley, who only joined the funny-videos-for-guys startup a year ago as chief marketing officer, has joined Yahoo as its VP of advertiser and partner marketing. He'd previously worked for a decade at Microsoft. We see the hand of Joanne Bradford in this; she's the former MSN chief who now runs ad sales at Yahoo. The pattern here?Yahoo has lacked a strong sales leader since the departure of Wenda Harris Millard, whom President Sue Decker disgracefully drove out of the company. With the hiring of Hadley to run marketing and Jeff Dossett to run media, Bradford is assembling her own team of loyalists, from Microsoft and elsewhere. In sales, personality rules. And every cult needs its leader. (Photo by Andy Plesser)
