I don't know what you mean by significant any more than Sean. But serendipity in a recommender comes from two sources. Both must be present. One source is having enough people who interact with the recommender. The second source is a judicious injection of exploration which can come from dithering of result lists or from additional exploration opportunities such as a top40 page or a rising star page or genre pages.
