What should we do with it? It's clearly not a "proper" question for the Stack Exchange network (highly opinion-based and a "big list"), but it's CW and nobody's had a problem with it so far.
- Close it (primarily opinion based, too broad, etc.)
- Delete it (possible, but not necessary)
- Put a historical lock on it (the small amount of content there probably isn't worth a lock at this point)
- Leave it as is (probably not the best idea, since people will think these discussion forum-y type questions are perfectly fine)
