Someone lock me up, this made me so emotional bro
AO3 Comments are SO SO SOOOOOOO important because you can only leave Kudos ONCE. You add to the hit count ONCE (every 24 hours).
So whenever someone updates their fic, the ONLY way an author knows who their regular readers are is if they comment on each chapter. And we WANT to know who's still reading.
Believe it or not, some of us think about the name that pops up constantly in the comments and go "omg I can't wait to see what they think of THIS SPECIFIC SCENE cuz I KNOW they'll say something about it!!!"
