Interact with your customer - this is how Mousehunt does it

"I think the main reason MouseHunt has become such a deeply engaging game is because we've included our users in the development of the game. We've done everything possible, used every method to get them to interact directly with us. The users have access to the development team (and each other) through the forums, videos, and a built-in chat system. We've decided to share a large slice of our office lives with them."

How could you do the same with your product?
