Ask HN: How does your company encourage internal product evangelism?

I am a product manager at a mid-size B2C company and I am brainstorming for ways to help others within the organization better understand our products and how they serve our customers' needs.

What practices does your company implement to get employees use internal products frequently? What are some good ways to promote the idea that product quality is everyone’s responsibility?

I am also open to suggestions how to build hype around products and product realeases internally. What are some concrete steps towards creating culture that has real passion for company products?
