There's nothing that prevents any list participants from starting more focussed or exclusive discussion groups, even ones bearing this name, with rules of participation and entry, standards, moderators etc. I can understand the impulse to want to separate the list's discussion from the conventional beat of mainstream news drums.
Far from wanting to impose some utilitarian imperative, yours truly appreciates the posts and content that in some way, shape, or form; from ensemble theories to descriptions and reports on the context, which they seek to describe... Reference a commitment to future world building, that is at least weakly discernible. It's fun to read which theoretical setups people prefer to describe the world, with or without ontological engagements. But what kind of world building we'd find on the other side of some descriptive-explanatory package - or arguments relating to demonstrating no connection at all - be such a package theoretical, ontological, or otherwise; do not seem off-topic entirely.
For example some kind of outlook with bearing on survival and sustainability such as:
Not that I'd endorse such... but to see such issues be completely disconnected from discussions relating to ensemble theories, would weigh more favorably towards Wittgenstein's "tempests in philosophical/academic teapots" argument and carry a cynical aftertaste imho, that seems less compatible with the drive that nourishes scientific inquiry. Because "why seek inquiry in scientific terms at all?", right? Therefore outlook, albeit gently and a sprinkle of breathable air and semi-digestible fibrous potential. PGC
