Thing 6- Social Bookmarking

My experience with Social Bookmarking has been great. JPB introduced me to del-icio-us a while back. However, I remember using it before then also. The tags for websites are helpful. Especially when I was trying to track down a song I heard in a commercial once. There is a secret society of website dedicated to tracking down rare music heard in commercials and movie trailers. Many people describe (or tag) these songs similarly: "The upbeat song in the Volkswagen commercial" is an example.
