Like meta.stackoverflow.com, I think we need a "Noise or Pointless" close reason on meta.math.
(Note: I am talking about the meta site, not the parent).
This sounds like personal exasperation and not an analysis of the actual discussions on the meta. I don't think the conversations have been as pointless or noisy as this feature-request indicates. If this "feature" is added for consistency with SO, so be it, but that decision seems more a matter of convenience for the SO software providers than a need based on the meta discussions to date.
