The mobile problem:

Last year, mobile constituted 60% of time spent on digital, up from 53% in 2013, according to ComScore. Yes, this mobile explosion is helping goose traffic at media sites. But they’re failing to monetize it quickly enough, resulting in a widening gap between mobile readers and revenue. At The New York Times, for instance, more than half its digital audience comes from mobile, yet just 10% of its digital-ad revenue is attributed to these devices.

Worth remembering as we think about Facebook’s new initiative. The mobile shift is happening so fast, publishing technology and business models are struggling to keep up. But that very speed means we have to get on top of this quickly.
