“I think an effective feedback loop is one where the customer cares deeply about what you're doing, and it clearly affects them or their business to fix a problem, change something, or whatever it is. Because the worst is the free customer, who gives lots of feedback. "I want this. It should do that." And because it's free, it has no effect on their business. They are not bought into it at all, so it's the worst feedback to listen to compared to that paying customer. I want to know the answer to the question, "If I create this feature, will you pay me more or will you stay longer?"”
