I'm sure that purely discussing whether something is off-topic is itself off-topic and should be moved there.
That's how communities work out what is right and what is wrong for themselves, Grumpy, by discussion. Only kids need to be told from on high how to behave and what may be talked about, because they haven't yet developed a sense of community nor of ethics. While there probably are quite a few kids on the forum, I'm pretty certain that the *vast* majority of people here are adults, and probably very capable ones.
I think peterpi said it best in post 15. While there is certainly an important duty in controlling spam posts and removing personal abuse, for the most part threads that have no community interest get left behind in the mists of time. There is no better moderator than the date stamp for deciding what matters to people. And it requires no effort to administer.
And even more importantly, it never creates ill feeling nor disenfranchises anyone in the community. That is paramount when building communities with very broad audiences, and that's what we're doing here.
Intolerance is a failure of education. Education is predicated on tolerance of the uneducated.
