That's all very intuitive to me. I want a tutorial that starts with "You want an app to do X with your friends, like an imitation of Doodle for planning Dungeons and Dragons sessions? The real way? Set aside $X money/month, book a domain name, and we're going to set up a real website, incrementally, and publicly available at every step along the way."

It's an environment conducing to pushing out stuff quick, not learning.
