This is quite possibly the least informative/descriptive post title I've ever seen. I don't have the vaguest idea what the post is about before clicking the link.
In an effort to help others, here is a summary of the article as I understood it:
Loyalty cards from supermarkets and other merchants do nothing to instill loyalty. Doing things that provide value to others is how you build loyalty. For example, Zappos linking their customers to their competitors when out of stock of a desired shoe, or the author providing his users with a data export feature from his application.
Hope that helps. If it did, feel free to give a quick upvote.
