The text explains it all.
I'd like to have this exist because serveral of our favourite thread got lost overtime, crushed by the trending threads as the thread we love got less popular.
We prevent this by bumping the thread up to make it to top again, again and again, everyday, every year, which is annoying so much.
I know this would cost much, but preserving out favourite post that world cannot recover is real platinum appreciation.
