Dawn Siff's 6-second Vine resume may be the world's first. Of course, in that time frame, she doesn't get much across. The entire text: "Idea machine Dawn Siff. Journalist. Strategist. Manager. Deadline Jedi." But Siff, who has 15 years experience at such places as Dow Jones and Fox News Radio, makes the most of it by way of illustration. For "strategist" she presents herself with a Rubik's Cube. The "Jedi" title prompts an appearance by a Light Saber.
