This is excellent advice. With every startup I've been involved with, the first iteration of our product was not the last, nor was it perfect. I see this more so as a means of ensuring your product doesn't get between you and the customer. Most startups simply do not value customer service as part of the opening strategy. Side rant: I blame Google for the perception that you can automate your entire business, without any human interaction. (Ever try to get support from a Google rep for an application?) Even Apple, who offers products that "just work", offers very good customer support.
