This will never happen because if SE implements an "off topic" section, then they will also have to moderate it. This takes from the purpose of this forum, which is explicitly to discuss the game. SE brought this forum online for only 3 purposes; for players to find information about the game, for players to discuss changes to the game (feedback), and for SE to communicate with the players. Off-Topic doesn't fall in any of those categories, so you're SOL I'm afraid. There are just too many cons to this idea and not enough pros (in SE's eyes).
