Abstract
We examine the challenges behind recommendations in social content sites. We use collaborative tagging sites (think del.icio.us, YouTube and Yahoo!Travel) as our application and report on our experiments in harvesting the collective tagging behavior to serve relevant content (think URLs, videos, travel destinations) to users. We address well-known and lesser-known problems in recommender systems such as over-specialization and data management for the masses. We conclude with open questions.
