Thematic is a new service designed for building and sharing visual stories. Thematic allows you to display up to twenty pictures organized around a theme of your choosing. You can add one line of text to each image in your story. Your completed story is displayed in a vertically scrolling format with each of your images occupying all of the available space in your browser. Completed stories can be shared publicly or kept private. Each public story can be shared via Twitter, Facebook, email, or embedding into a webpage. I've embedded my sample story below.
This can be a great tool for aiding content marketing
