The FollowUp button is a unique feature that allows readers to subscribe to follow a story.
A reader clicks the FollowUp button, provides an email address, and confirms their subscription.
If the BackStory is known for that story, we'll send an algorithmic timeline of stories about that topic or storyline to the reader immediately.
Then, when a follow-on is detected by our algorithms we send the reader an email alerting them to the new story. No editorial work is needed, other than writing great stories that readers want to follow.
