"Interesting. Maybe you have changed your POV, but last time we discussed Creationism you were an inerrant-Bible Young Earth Creationist."
More or less, I am (a posteriori). My point is that your understanding of the position is skewed.
"Taking Genesis as literally true, God created the Earth, the heavens, the sun and moon, plants, animals, and man as deliberate conscious acts. Even Eve, a single individual, is intentionally created by God."
Yes, but that is not the same as 'micro-managing' at all. That is closer to your grand architect image.
"It's difficult to imagine more of a micro-managing Creator than the literal Genesis version of God."
It's not micro-managing at all.
"On the other hand, most IDers assume a God tasked with "macro-evolution", and allow for "micro-evolution" to be delegated to God's laws of nature."
Right, but this is actually more akin to micro-managing than the YECcer POV, as it requires God to step in on occasion and tweak the system to get the outcome he wants.
"As I suggested in my last post, IDers could just make the next step and allow for a God-as-architect: a Grand Designer, not a tinkerer. Then evolution fits right in."
And so would Young Earth Creationism.
I started a whole thread to detail what this all involves, but I would say to you here that your primary misunderstanding isn't even so much YEC but what a Christian means when he says 'God.' God is the sum of all that is real, and his derivative creations do not exhaust what he is. Nothing can exist apart from his willing it, and nothing can exist apart from his essence. Given this definition, your underlying assumption on this matter that somehow the matter of the universe exists eternally alongside of God and God can come in and 'tinker' with it is 100% flawed. Given this definition, there has to be a point in which God initiates the origin of a thing.
Your apparent conception is not new. It is quite old. It is more akin to Greek mythology and the Demiurge and chaotic matter.
