I've dug my last drywall screw out ...no
more for me.

:-) Same act, different stage. Their high hardness/brittleness is
problematic enough, but here in the NE US our rain is often as acid as
ph 4, and in a lot of exposed uses they seem to suffer from added
corrosion embrittlement (observed but not proven), and also often do
waste through enough in a few years to fracture off in acidic woods
like our read oak. Seem to be a false economy all the way around,
afloat or ashore - YMMV. But then again, I'm the kind of guy who
thinks drywall is a dumb, useless material, too (except as a fire
barrier). :-)
