"7 reasons our app is overpriced" should be the right title for this post. I love the last point :

> A good programmer in the UK costs about $ 40 an hour. If an app sells for $ 10 that only pays for about ten minutes of a programmer’s time. Therefore, spending more than ten minutes interacting with a customer who bought a $ 10 app effectively results in a loss on that app sale.

So you define the price based on how much time you interact with a single customer? It just doesn't make any sense at all. And that kind of logic does not scale if you have thousands of paying customers, since your time with each of them drops to zero.
