You can follow Threads and the Wall itself. If you're following the Wall, you get a notification on all new threads (and replies to them). If you follow a Thread, you only get notifications on those threads that you follow. I haven't tested, but I believe if you unfollow a Wall, you still follow the threads you've replied to before (with an auto-follow). If not, yes, you can re-follow the threads you'd want to pay attention to.
