1) Supporting a product requires anticipating how users will find help and information on using it through things like the new user experience, documentation, and use cases. 2) It is important to constantly improve the user interface and documentation based on watching how users actually use the product and identifying pain points through analytics. 3) When responding to customer support requests, the goal should be to help the user help themselves as much as possible through education, focusing on a positive tone, and offering solutions even if the problem is not directly with your product.
