Yahoo properties have been going through a series of quick revamps under the direction of Marissa Mayer, and the latest sign of change comes as a major new hire for Yahoo News. Megan Liberman, previously a deputy news editor for The New York Times, will begin today as editor-in-chief of Yahoo's news division. Though a large portion of Yahoo News' content is aggregated from newswires and partner websites, it also includes its own reporting. Liberman will be focusing on those original reporting initiatives, including adding in additional video content and coverage of live events. It's a seemingly big talent grab, and it could be the next move in turning the struggling internet giant around.
