I have tried to contact them, but I haven't got any reply from them. It seems they don't manage the site these days. If anybody know the current statues of the site, please let me know it. I will appreciate your help.

BTW, I read a paper (FOAFING THE MUSIC: A music recommendation system based on rss feeds and user preferences) about this site. In this paper, the author explains how the music recommendations are generated in the system. At first the system get interests from user's FOAF profile and detect artists and bands. And then, the system select related artists, from artists encountered in the user's FOAF profile and rate results by relevance. The following figure is the recommended artists from artists detected in a user's FOAF profile.
To get the artist's similarities, a focused web crawled has been implemented to look for relationships between artists (Such as: related to, influenced by, followers of, etc) . If the system detects the following artists from the user’s profile: Dogs d’Amour, Social Distortion, The Misfits and The Pogues. Starting from these artists, the system searches for similar artists and for artists influenced by them. Then, it scores them in terms of counting artist occurrences.

The author, Lorrie Faith Cranor, is one of famous person in privacy research area. She is one of authors of P3P and APPEL Specification. In this paper, she outlines the privacy risks associated with personalization and describes a number of approaches to personalization system design that can reduce the privacy risks. Privacy risks can be reduced when personalization system designs allows for pseudonymous interactions, client-side data stores, and task-based personalization. In addition, interface that allow users to control the collection and use of their profile information can further ease privacy concerns. Pseudonymous profiles are a good approach when personalization information need not be tied to personally identifiable information. Client-side profiles may are useful when personalization services can be performed on the client. Task-based personalization may be appropriate when knowledge of a user's historical profile does not significantly enhanced a personalization service. Interface that put users in control of the collection and use of their data as well as the types of personalization systems more privacy friendly.
