Sucking all the air out of the room? Or just filling a void? I suspect the latter. I doubt that the O.T. threads are displacing legitimate Machine threads. Things slow down in the (northern hemisphere) summer. Seems like those down under need to fill the gap.

Theory & Practice-
Theory is when you know something but it doesn't work.
Practice is when something works but you don't know why.
It it dangerous to combine Theory & Practice;
nothing works and you don't know why.
