Ask to be put on frontline email/phone customer support for your product a few times a year. Hearing problems/complaints directly from the voice of the custome

Ask to be put on frontline email/phone customer support for your product a few times a year. Hearing problems/complaints directly from the voice of the customer, then having to explain a sometimes cumbersome workaround to solve them, is invaluable. Plus you buy goodwill with your support team for walking a day in their shoes.
