This might very well be something you've already thought of, and it doesn't look like there any such articles on your site so far, but if you're thinking about expanding, I'd be very careful of excluding all r/OrphanCrushingMachine type stories. I.e., stories that sounds uplifting and happy, such as "grade school student pays off the lunch debt for their entire class" without addressing the bleak reality that our society has put children into debt.
