Creating customer evangelists

The excellent book Naked Conversations quotes the book Creating Customer Evangelists and states that if you want your customers to be evangelists for your business you must:

1. Continuously gather customer feedback.
2. Make it a point to share knowledge freely.
3. Expertly build word of mouth networks.
4. Encourage communities of customers to meet and share.
5. Devise smaller offerings to get customers to bite.
6. Focus on making the world, or your industry, a better place.
