A total of 13 major publishers are involved in the pilot, including the Boston Globe, Chicago Tribune, Seattle Times and San Francisco Chronicle.

It's no secret as to why Facebook would be willing to mount this campaign. It could help boost Instant Articles subscriptions among the newspapers still involved in the service, and may reassure publishers that it still supports them. And of course, fostering the growth of established, respected news outlets could help fight fake news. The question is whether or not this will teach publishers enough to make a difference -- and, for that matter, whether or not it will bring back publishers burned by Facebook's past decisions to downplay news stories. Facebook has been quick to acknowledge that it hasn't always been cooperative with publishers, but education by itself might only do so much.
