With all the nostalgia of the early App Store and iOS SDK days, Frederik Riedel tweeted about his experience developing iRedstone:
When I created iRedstone, I had no idea what object oriented programming was. I had no idea what a ViewController was. It was all in one UIView. But it worked. You don’t have to be an engineer to create apps.

After he tweeted that, other developers started quoting it, and sharing their experiences. Frederik has compiled a great collection of them over on his blog.
