That is all fine and well, but from a List-Managers standpoint, the governing principle seems to me to be that list software should allow these choices to be made on a per-list basis, not interfere with them or attempt to mandate a "one size fits all" answer.That's fine for many, even most, lists. We host a few where the goal is comunity, even "jabber," not technical or focused discussion. The owners of some of these lists even impose a minimum daily or weekly posting requirement; others don't go so far, but want to make it clear to everyone that if they intend to stick around and overhear what others are saying it requires a deliberate "allow me to stay in the room even if I'm not talking" process.
With specific reference to the double-confirm issue, it is appropriate for some lists, some clienteles, and some situations, and inappropriate for others. List administrators should be able to choose whether they want it or not.
