Older posts will get lost no matter what the format is.
This way, a thread with new responses will be brought to the top. As long as the subject is actively being discussed, it will remain on the first page. Otherwise, if the subject is on page 2 or 3 or more, a new thread will need to be created. This way, if you are searching for a subject, it is much easier to follow. No need to search through multiple threads with only a couple of responses.
Virtually every other forum does this, and I applaud Hans for updating the forum.
