You should probably also keep in mind that this isn't a consumer app. Who ever uses this will have seen the entire process before and tested it in a training environment. The redesign seems mostly to focus on making sure stuff isn't done by accident.
Great writeup, though I have to be completely honest here and say that I love Patrick's writeups for independent hackers, makers, micropreneurs, bootstrappers etc. His writings and practical case studies gave me the power, as a nobody, to make tens of thousands of dollars in order to be more with my wife and child, while doing the work I love. I kind of miss those essays.
