Snapchat just showed how serious it is about turning its mobile video messaging service into your news hub. The company has hired Peter Hamby, one of CNN's best political reporters, to oversee its news efforts. He'll still contribute to the TV network through 2016, but his top priority will be the internet startup. As to what Hamby will actually do in his new job? He's not spilling the beans, but his interest in Snapchat's live stories suggests that you'll see more on-the-ground coverage of unfolding events. You may well find yourself using a single app to both catch up on the day's happenings and share gossip with your friends.
