Over the last five years a range of projects focused progressively more elaborated techniques for adaptive news delivery. However, the adaptation process in these systems has become more complicated and thus less transparent to the users. In this paper, we concentrate on the application of open user models in adding transparency and controllability to adaptive news systems. We present a personalized news system YourNews that allowed their user to view and edit their interest profiles and report a study of the system. Contrary to our expectations, the study demonstrated that this ability to edit user profiles can harm the system and user performance and has to be used with caution.
