From the quotes above, It seems to me you prefer theory over practical knowledge,
I wonder how the first foamie and PMF builder was received. With all due respect, I prefer to study the lessons of practical knowledge but I also believe in experimenting and looking at things in different ways. At least in this "leisure time" endeavor, where I'm doing the work, I don't have the resistance of a contractor, like I do as a design professional when I specify that something be done in a new way. Contractors hate that.
I do respect your views and appreciate you taking the time to discuss this, and admire your work.
