Some forums hate thread resurrection. For good reason, some types of topics aren't well suited for resurrection. For example an old question topic that is answered isn't the greatest place for a new question.
But some discussion topic types are better suited for this, they may be timeless in subject matter and there may be more to say on the subject.
The next A2K will help this kind of thing technically (e.g. maybe the questions topic type gets closed after an answer) but till then I wanna have fun resurrecting great threads.
Here's one I did today:
National Myths-Stereotypes
Why? Because while having dinner with fbaezer in Mexico City he mentioned it in passing, telling me how he had fun talking about regional Mexican stereotypes when the thread wasn't going anywhere.
It sounded like a great thread and it is, and today I happened to remember an appropriate joke and the thread at the same time to resurrect it.
So find an old gem, and resurrect it and let us know about it here.
