Former Guardian deputy editor Janine Gibson has joined BuzzFeed UK as editor in chief. Gibson, who left The Guardian last month after unsuccessfully applying to replace Alan Rusbridger as editor in chief, starts on 1 August. She was editor of Guardian US during the time of the Edward Snowden revelations two years ago and more recently was put in charge of the Guardian Web site. In an announcement to staff, current BuzzFeed Editor in Chief Luke Lewis said he would be moving to become executive editor.
