But what I would request is so many people request writers to send the a heads up when a new chapter is up on IF in a form of a Pm. People who do ask for those the least the can do is comment coz not only is the writer updating a story but taking the trouble to send you updates which takes more time.
Given that if you become disinterested simply remove yourself from the buddy list it's a system which works for both I guess and causes less dissapointment for both parties.
But in general if you do enjoy a particular writers work and regularly read I think it's only fair we give our feedback it's a beautiful gesture and I am sure will make everyone feel really good.
