There's a lot of material to cover, much already done but needing improvements, distillation and summarization, perhaps here. I'm not sure how many posts it's wide to create, and in what order. Here I'll let readers suggest issues they'd like to add to, or see covered. Each new post gives me space (if not time) to explain. And it gives readers comment space, and defines what it is. So let me know what comments or questions you have and I'll create a space for that.
