The discussion is still relevant.
As to this thread. I am happy with no one performing the role of gatekeeper. This role was essentially to exclude books from publication. This role has gone, never to be resurrected. The problem now is choosing from a variety which may as well be infinite. I have found very few problems in excluding what I think is the real garbage.
