Centralised Social Bookmarks

Del.icio.us http://del.icio.us/is a site on the oul' Interweb http://www.answers.com/interweb . It's a centralised way to manage your bookmarks and socially share them via members statistics and access via RSS http://www.answers.com/rss .. pretty neat as I was using Gmail http://www.gmail.com/ as a sorta' deposit/resource for these kind of bookmarks...
