Because of the way threads are presented (oldest first) reanimated threads have a habit of giving a bizarre impression of progress - until you take the time to look at the posting date of the first item.
By automatically "archiving" older threads the search engine is relieved of a considerable strain and works better. The forum is quicker and these threads remain available (via search) for the information contained.
After the "use by" date has passed it is, arguably, as well to start a new discussion - fresh and tasty."
Couldn't have put it better myself.
