This is definitely not the time for this, as you have far greater things on your plate to deal with, but I'll forget otherwise...
In the forums, when you reply to someone, the reply is shown to be an offset to the comment replied to. This is a great visual layout and makes reading the forums and subsequent replies a doddle.
Is it possible to make this layout applicable to the comments on stories? At the moment, comments are just one long list with any replies denoted by '@' in front of the name of the person who is being replied to. Depending on the how many comments and how often the author replies to those comments, you might need to go for a digital scroll to find the comment being replied to.
Having replies more visually attached to the commentator like in the forums, looks better and, I don't know, it just seems more... personal... than the '@' sign when you are responding to comments.
