It truly is a waste of time when detailed discussion, aimed to establish and obtain consensus, is hidden from view. I have unhidden the latest discussion on the collaboration of the lead, not that I consider the previous versions irrelevant, because all those sections include the discussion that has generated the consensus behind the comments detailed in the latest version, but because with all the diversion tactics going on here, it may be useful to have only the current version more clearly on display. Note that the discussion here is about the general introduction, and that controversy has focussed on only one word within that - that's a great shame but no need to prevent the inclusion of all the other delicately explored points that have been discussed to find the best general agreement.
