Thing is, without thread bumping new users know they won’t get any reply to their question by asking in an old post and with the discussions not being continuous only the person replied to is warned that a new message was posted.

I wouldn’t have come back here if I didn’t get a notification that you replied and I’m not checking the whole discussion to see if there’s anything else that’s new. If it was a forum instead I would have received a warning of you quoting me and I would have went back to the conversation starting where I left off.
