To be entirely fair, the signature spam, and related nonsense posts is fairly unpleasant...

My issue with the ivory tower is that its placement within the forum more or less makes it an off topic section that allows for a broad variety of threads that I may not be interested in reading. I would say I would rather have the ivory tower be a child of bitcoin discussion, and allow any non-marketplace, bitcoin related threads, even if said thread would also be appropriate in technical discussion, trading discussion, and similar.
