It's a way to follow up on stories that bubble up on Reddit's frontpages and give them more depth. 202M+ people can do a great job surfacing and discussing content in real-time, but our awesome editor, Vickie, and her team can do a much more effective job following up on those stories, interviewing, and adding more substance.

E.g.,

This photo of an unemployed man handing out resumes went to the top of r/pics: https://www.reddit.com/r/pics/comments/3kc1sh/this_man_lost_...

We interviewed the guy pictured + wrote about it: https://www.reddit.com/r/Upvoted/comments/3kxp7q/bottom_of_t...

Then a week later a photo of the guy (now with a job) topped on r/pics again and a random redditor linked to our story to provide context for everyone on the thread:

https://www.reddit.com/r/pics/comments/3lv1b3/way_to_go_redd...

This was back when we just posted as selfposts to r/upvoted, so I suspect that same article in a beautiful blog layout: http://upvoted.com/2015/10/03/donnie-grooms-unemployed-busch...

Would do even better and reach even more people!
