People talk a lot about it in the abstract, and there is a lot of armchair quarterbacking. I suppose all of that has a smidgen of value, if nothing else to set expectations of people starting out. On the other hand, very few people with truly detailed internal knowledge talk about the why's and how's, especially avoiding 20-20 hindsight. It's a difficult enough thing to do objectively for yourself, and sharing it takes that up a notch. Especially when you're all but guaranteed to have a bunch of people tell you how you were obviously idiots; many of them having never so much as tried to build something new.
