AOL, Inc. (NYSE:AOL) is having a hard time retaining some of their talent. Within the last couple of days, AOL saw Brad Garlinghouse and Sarah Lacy leave the company. Now former TechCrunch CEO Heather Harde is leaving the company. Harde became an executive at AOL after technology blog TechCrunch was acquired. It is believed that Harde was pissed when a Huffington Post CEO sent out an e-mail bashing TechCrunch founder Michael Arrington.

AOL announced yesterday that the company’s ad chief Jeff Levick is stepping down, with Ned Brody stepping up as Chief Revenue Officer and President of AOL Advertising. Jeff Levick only held the position for two years, and the changes in the organization follow declining advertising revenues. Lauren Hurvitz (head of PR) and Kathy Andreasen (head of HR) are also leaving the company, while five new general managers have been announced: Chris Grosso for AOL.com, Brian Kaminsky for Huffington Post, Kerry Trainor for Entertainment, Jay Kirsch for Marketplace and Heather Harde for Tech.
