  I cannot understand why Delicious team doesn't implemented collaborative filtering [1]. I think this is the main benefit that the user can get from a social bookmarking site - the ability to see the "bookmarks of others that are similar to your bookmarks". The implementation is not too complex and nicely covered in the book [2] with examples in Python. The book even has a special section "Building a del.icio.us Link Recommender". If I'm not mistaken, there were prototypes for doing collaborative filtering of Delicious dataset written by standalone applications. But doing such filtering requires direct access to the database and cannot be done efficiently via HTTP. So, after the current team had bought Delicious from Yahoo, I thought that implementing collaborative filtering would be their main priority. Instead of that, they concentrate forces on worsening and cluttering UI experience along with breaking various Delicious bookmarking plugins for popular browsers.
