It's annoying. Currently, when a post is automerged, then the original date/time of the post takes on the date/time that it was merged. So say that I make a post a week ago...if I'm the first person to post in it again, then it is automerged, it looks like I just made the original post instead of posting a 2nd time. I think that the post should maintain it's original time/date...and when it is automerged then it be added in the edit text at the bottom of the post. And maybe not even automerge posts that are more than a few days apart anyway.
