There serendipity encountered in the stories in this thread is essentially just different on one axis: it's not "personalized" or otherwise user-aware, it's content-driven active organization and presentation. That system can have its own ways of breaking down - consider trying to curate a collection of books on a topic you don't know about - but it gets at the limits of our current algorithmic approaches. Our systems don't know the content itself, just the feedback various others give about the content.
