I am pretty sure that there should be a certain dynamic relationship between the thread intention and the thread content. Dogs and cats aside, in a speculative topic named "Looks like [something] is almost out", a lack of references to the PR1.2 thread and Chuck Norris would require Ingsoc moderation. In a post-release thread discussing how to rewrite a module to fit into the touch UI, I would believe there would be less acceptance for subthreading. TMO is a community, not a FAQ slash work log.
