Great post!
All this stuff, in principle, provides the basic foundations for a lot of work I hope to see happen more in the future... but in my travels, the systems thinking landscape is quite varied, technical, and inaccessible.
Nonetheless, I though it would be a good idea to pull together what's been shared and written so far w.r.t. ST, but more from a designer-ly point of view and wrote this post below.

I'd be curious to know how much of this overlaps with your thinking around systems thinking (or, systems practice) for designers.
