Is there currently a way to subscribe to a given user's comments? If not, is this feature perhaps under consideration? I imagine many of us would find it hugely helpful.
In a cursory search, I came upon this:
Retrieve Comment Threads for a user
URL: http://api.ihackernews.com/threads/{userID}
Method: GET
Returns: array of comments {children, comment, id, parentID, points, postedAgo, postedBy, postId}
but it seems to be down (based on the comments, perhaps for some time).
