Never close something if it only might cause dramas. If we did that, half the internet wouldn't exist. There was a practical discussion ongoing about the effect our admin creation policy was having on user confidence in this wiki, and closing the thread could be seen as a way of silencing dissent rather than addressing the problem head-on. As a general rule, don't close a thread unless
 * It's a policy decision which has been completely concluded, including finalising implementation details (and even then, there's generally no harm in leaving the discussion open) or
 * The thread has actually descended into drama to a point where it can't be brought back from the edge.

As a general rule, I believe it's best not to close threads unless there really is no other option. There's generally little benefit and can stifle important discussions. While it is just my opinion, and you may choose to ignore it, I think it would be best to try to avoid closing threads unless absolutely necessary. The possibility of things maybe perhaps potentially deteriorating is not a good enough reason to close a discussion. If it's not valuable, the conversation will die a natural death without admin intervention.
