It seems this post has now been removed from the front page. I understand your reasons for not wanting to have two similar discussions simultaneously. However, the two posts paint two different sides of the same story. How are people going to read this side of the story if it's been hidden?
The top subthread there links to this post, and the top several subthreads are substantive defences of its position. Anyone who wants to read the other side of the story will have little trouble finding it.
Oh, I haven't spotted moderation in action before. Does this mean this thread will be merged into the old one? Or will it be removed?
Normally we do that, but the specific comments in this thread wouldn't make sense in the other one. So it's probably not a good idea this time.
The obvious solution is to support aggregating related URLs, and we will do that eventually, but there are other things that need to be done first (I don't just mean that have higher priority, but that are literal prerequisites). In the meantime, it's partial manual fixes for the lot of us.
Normally the thing we do with rapidly developing stories, i.e. when a new post adds significant information, is bury the previous thread and leave the new one up. But my sense is that people wouldn't prefer that in this case, and since the current post is already being discussed in (edit: at the top of) the other thread, we'll leave that one up instead.
