Maybe. ---
Well, I like to join movie threads and actually a certain poster just made up a few of them. They stay for (say) some days on the first page. Then they go down the drain of OT. No problem here, but a few days later, a "new" thread with the very same title/content shows up. Such thing could surely happen to other issues as well, but movie related stuff *seems* to be very popular, so that subforum idea came to my mind.
