Yes I do realize that the comments are primarily meant to introduce improvements in the post being commented on. And also that if any subsequent commenters want my feedback, they will @ me explicitly. But even if this is not done, I would prefer to know about subsequent activity around the post which I commented on. Maybe the @ has been forgotten, or maybe there are some other reasons for me to react to further developments. I gather right now the only way is to revisit my comments via the activity tab. Could I be notified when any kind of activity of mine has been followed by some other activity?
Besides, in some (maybe indirect) way my comments may result in, say, edits of the post without me being notified. Could that be detected somehow too?
