I would very much like to see the "That's already been discussed" comments shut down. It shuts down conversation, and it makes members who have been away for some time, and newly returning, like we've been told to shut up. I can only imagine how it makes new members feel. One of my fave threads is dying, and I saw that said to a newbie. Wow. Easy to see why it's on it's way out. That's just sad.
