It's not necessary that we all do; it's only necessary that some of us
(preferably more than one, but at least one) know enough to make
reasonable choices on any one point.

The fact that there isn't *anyone* stepping up to do that investigation
or make those decisions. If someone steps up to the plate, I'll be glad
to give all the moral support we can. In the absence of someone
actually volunteering to do the work, this whole discussion is
pointless.
