Dien,
Another good reason to change the forum to implement "threaded" views is so particular posts within a thread can be referenced directly to another related post. It can't be done now on the new forum, as each post does not have a separate ID number whereas the old forum did like the forum example you posted. In other words, you can only carry over the entire thread to reference it elsewhere.
Hopefully, this makes some sense and at this point it looks like the Red team is winning with a three quarter Vote.
