This made me ponder.. what aspects like Youtube does IG have to help with distribution? I think they removed the "your friend liked this photo" type feed right? Beyond that all I can think of is 'tags'. (Maybe tags help significantly because people 'follow' tags?)

I do see that they encourage discovery in 'Reels' but not sure about regular photos
