maybe the best PG ever? So short and sweet. Follow these simple rules and you can succeed, don't and your startup will die. The customer service one was a surprise for some reason, not that it does not make complete sense but not something I would immediately associate with HN/YC. Its just so important to be above and beyond with early customers, helping customers is the best way for founders to stay connected with what matters and learn what they should be doing. its a godsend of insight for making something people want.
