Hello,<p>I have recently started doing a PhD in Information Systems. My general research subjects are User Modeling/Information Filtering/Recommendation Systems. I will also try to look at those subjects from a mobile point of view.<p>Which "burning" topics/problems do you know that exists in this field?
Which issues/directions would you recommend focusing on?<p>Thanks,<p>Liu

Why is it that people get stuck? I'm stuck. I feel it. 90's metal is all I listen to willingly (current British pop hitting my ears is GF's fault). There are "generations" of music and people just stop liking new songs. They feel unfamiliar.<p>Apply the same to a world view(news, politics) or anything really. How do we make recommendation systems that allow users to grow their tastes?
