The Wall Observer thread is in Speculation, so when you start using it for any off-topic thing that comes to mind, the posts get reported and then deleted. This has happened too much and for too long in the Wall Observer thread.
Maybe it'd be OK from our perspective to move the thread to Off-topic and then let people use it as they wish, but is that what the posters there really want? I just don't get the point of the thread. If you want to talk off-topic, you can create multiple dedicated threads in Off-topic.
