Twitter's head of news leaves after just a year in the job

Though Twitter is now a huge part of the news cycle, it's still figuring out how to handle it internally. Vivian Schiller has just stepped down as the head of news there, almost exactly a year after she took the gig. Having worked at NBC, the New York Times and CNN, Schiller was brought on to help the social network foster ties with major news outlets. She announced her resignation in (of course) a series of tweets, and Twitter broke the news to its employees in a memo obtained by Re/Code. The document was full of praise for Schiller, citing numerous new media partnerships and Dataminr integration under her stewardship. It also revealed that the resignation came about after Twitter merged its news, government and election teams. The newly formed division will now be led by Elections and Government head Adam Sharp.
