It works as follows: each time Webu shows you a web page it will offer you the chance to rate the page on a scale of "totally irrelevant" to "very relevant". As you indicate your preferences for or against particular types of content, Webu will start to learn about the kind of stories that interest you and will start to show you other articles it thinks you may find interesting. The more you provide feedback, the more it will learn about what interests you.
