Tablet readers typically give a story about 78 seconds before deciding whether to keep reading or to start looking for a new story. The team suggested designers give readers a "gold coin" at the 78-second mark (what the team called the "bailout point") in hopes of keeping readers engaged. The gold coin might take the form of a pull quote, picture, graphic, or link to another story, anything to keep the reader reading. By way of example, think about Time.com's tendency to include graphics and stand-alone links to other stories between paragraphs.
Scanners v. methodical readers -- About 75 percent of digital natives (those between 18- and 28-years-old) read used a "scanning" style to consume news on a tablet. Interestingly, this doesn't mean they don't read or read less, they just have a different search method. It's style of consumption, not amount of consumption.
