I wonder. Considering it would be easy for HN maintainer to implement this feature I came to the conclusion they considered it and chose not to go with it. Maybe because that would somehow degrade the HN experience. Maybe that would shape a `quick-reply-on-the-spot&#x27; tendency instead of people getting back to the comments a few hours later to check out if the conversation brought new insights. A mean to keep some kind of posters from over posting.
