Who am I addressing?

There are discussions with several participants, where someone is responding to a comment a few posts up. It's hard to tell which comment he's replying to. The vertical grey lines to the left of the comments give some clarity, but it's often ambiguous, particularly as new arrivals chime in, and will become more so with a larger audience.

I've seen other platforms address this by having the default first word of a reply be the bolded handle of the person being responded to. This can be deleted if the comment is intended for the general discussion rather than as a reply to a specific individual. Adding this feature might enhance social bonding among diggers.
